Get lost or forgotten password for PST file

July 6th, 2011 admin

Microsoft Outlook is a personal information manager from Microsoft, available both as a separate application as well as a part of the MS Office suite. Although often used mainly as an e-mail application, it also includes a calender,task manager, contact manager,note taking, a journal and web browsing.

Password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource. The password should be kept secret from those not allowed access.

Password security architecture

Common techniques used to improve the security of computer systems protected by a

  • Not displaying the password on the display screen as it is being entered or obscuring it as it is typed by using asterisks (*) or bullets (•).
  • Allowing passwords of adequate length. (Some legacy operating systems, including early versions of Unix and Windows, limited passwords to an 8 character maximum reducing security.)
  • Requiring users to re-enter their password after a period of inactivity (a semi log-off policy).
  • Enforcing a password policy to increase password strength and security.
    • Requiring periodic password changes.
    • Assigning randomly chosen passwords.
    • Requiring minimum password lengths.
    • Some systems require characters from various character classes in a password—for example, “must have at least one uppercase and at least one lowercase letter”. However, all-lowercase passwords are more secure per keystroke than mixed capitalization passwords.
    • Providing an alternative to keyboard entry (e.g., spoken passwords, or biometric passwords).
    • Requiring more than one authentication system, such as 2-factor authentication (something you have and something you know).
  • Using encrypted tunnels or password-authenticated key agreement to prevent access to transmitted passwords via network attacks

Outlook Password Recovery

If you’ve forgotten your Outlook PST password or Mail account passwords? Then outlook password recovery tools are used to recover the lost passwords.

Let’s have a brief look at the outlook password recovery main benefits:

  • PST file passwords are recovered instantly;
  • Mail account passwords are recovered instantly;

PDF- Portable Document format

July 5th, 2011 admin

Portable Document Format (PDF) is an open standard for document exchange. This file format created by Adobe Systems in 1993 is used for representing documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.

PDF was originally a proprietary format controlled by Adobe, and was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008.

The extension of the file is .pdf. This format was developed by Adobe ® Systems for ease of document sharing on the Internet and for easy printing of documents. It retains the original layout of the document when converted to a PDF file and is a very secure way of sharing and publishing information on the Internet.

PDF is an open file format specification; it is available to whoever wants to develop software utilities for managing, creating, accessing or viewing PDF documents. Adobe ® offers a free reader to view PDF files.

Adobe soon started distributing its Acrobat Reader (now Adobe Reader) program at no cost, and continued supporting the original PDF, which eventually became the de facto standard for printable documents on the web (a standard web document).

File structure

A PDF file consists primarily of objects, of which there are eight types:

  1. Boolean values, representing true or false
  2. Numbers
  3. Strings
  4. Names
  5. Arrays, ordered collections of objects
  6. Dictionaries, collections of objects indexed by Names
  7. Streams, usually containing large amounts of data
  8. The null object

LAYOUTS TO THE PDF FILES

  1. non-linear (not “optimized”)
  2. linear (“optimized”).

Non-linear PDF files consume less disk space than their linear counterparts, though they are slower to access because portions of the data required to assemble pages of the document are scattered throughout the PDF file.

Linear PDF files (also called “optimized” or “web optimized” PDF files) are constructed in a manner that enables them to be read in a Web browser plugin without waiting for the entire file to download, since they are written to disk in a linear fashion.

Security and Signatures

A PDF file may be encrypted for security, or digitally signed for authentication. The  standard security provided by Acrobat PDF consists of two different methods and two different passwords, “user password” and “owner password”. A PDF document may be protected by password to open (‘user’ password) and the document may also specify operations that should be restricted even when the document is decrypted: printing, copying text and graphics out of the document, modifying the document, or adding or modifying text notes and Acroform fields (using ‘owner’ password). However, all operations (except the document open password protection, if applicable) which are restricted by “owner” or “user” passwords are trivially circumvented by many commonly available “PDF cracking” software and even freely online, and if circumvented these restrictions no longer let the author control what can and cannot be done with the pdf file once distributed. This warning is also displayed when applying such restrictions using Adobe Acrobat software to create or edit PDF files.

Even without removing the password, most freeware or open source PDF readers will ignore the digital rights management ”protections” and will allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection.

Technical issues

Accessibility

PDF files can be created specifically to be accessible for disabled people. Current PDF file formats can include tags (XML), text equivalents, captions, audio descriptions, et cetera. Some software can automatically produce tagged PDFs, however this feature is not always enabled by default. Leading screen readers, including JAWS, Window-Eyes, Hal, and Kurzweil 1000 and 3000 can read tagged PDFs; current versions of the Acrobat and Acrobat Reader programs can also read PDFs aloud. Moreover, tagged PDFs can be re-flowed and magnified for readers with visual impairments. Problems remain with adding tags to older PDFs and those that are generated from scanned documents. In these cases, accessibility tags and re-flowing are unavailable, and must be created either manually or with OCR techniques. These processes are inaccessible to some disabled people. PDF/UA, the PDF/Universal Accessibility Committee, an activity of AIIM, is working on a specification for PDF accessibility based on ISO 32000.

One of the significant challenges with PDF accessibility is that Adobe Acrobat is capable of presenting PDF documents in three distinct views, which can be inconsistent with each other for a variety of reasons. Acrobat offers three views:

(i)                the physical view,

(ii)              the tags view, and

(iii)           the content view.

The physical view is displayed and printed (what most people consider a PDF document). The tags view is what screen readers read (useful for people with poor eyesight). The content view is displayed when Acrobat’s “Reflow” tool is invoked.

There is much confusion on the subject of whether or not Acrobat’s “reflow” tool is relevant to accessibility since it does not process the tags tree, and thus cannot correctly represent content that flows between pages. Some feel that the reflow tool is useful for people with mobility disability, and thus take the view that for a PDF document to be accessible, Acrobat’s three views must be consistent with each other In reality, the “content view”, and thus Acrobat’s Reflow tool (as of Acrobat X) displays the PDF’s rendering rather than logical order, and is thus irrelevant to accessibility.

Viruses and exploits

PDF attachments carrying viruses were first discovered in 2001. The virus, named “OUTLOOK.PDFWorm” or “Peachy”, uses Microsoft Outlook to send itself as an attachment to an Adobe PDF file. It was activated with Adobe Acrobat, but not with Acrobat Reader.

From time to time, new vulnerabilities are discover in various versions of Adobe Reader, prompting the company to issue security fixes. Other PDF readers are also susceptible. One aggravating factor is that a PDF reader can be configured to start automatically if a web page has an embedded PDF file, providing a vector for attack. If a malicious web page contains an infected PDF file that takes advantage of vulnerability in the PDF reader, the system may be compromised even if the browser is secure. Some of these vulnerabilities are a result of the PDF standard allowing PDF documents to be scripted with JavaScript. Disabling JavaScript execution in the PDF reader can help mitigate such future exploits, although it will not provide protection against exploits in other parts of the PDF viewing software. Security experts say that JavaScript is not essential for a PDF reader, and that the security benefit that comes from disabling JavaScript outweighs any compatibility issues caused One way of avoiding PDF file exploits is to have a local or web service convert files to another format before viewing.

On March 30, 2010 security researcher Didier Stevens reported an Adobe Reader and Foxit Reader exploit which runs a malicious executable if the user allows it to launch when asked.

Usage restrictions and monitoring

PDFs may be encrypted so that a password is needed to view or edit the contents. The PDF Reference defines both 40-bit and 128-bit encryption, both making use of a complex system of RC4 and MD5. The PDF Reference also defines ways in which third parties can define their own encryption systems for use in PDF.

PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing or printing. The restrictions on copying, editing, or printing depend on the reader software to obey them, so the security they provide is limited.

The PDF Reference has technical details for an end-user overview. Like HTML files, PDF files may submit information to a web server. This could be used to track the IP address of the client PC, a process known as phoning home. After update 7.0.5 to Acrobat Reader, the user will be notified “via a dialogue box that the author of the file is auditing usage of the file, and be offered the option of continuing.

Through its Live Cycle Policy Server product, Adobe provides a method to set security policies on specific documents. This can include requiring a user to authenticate and limiting the timeframe a document can be accessed or amount of time a document can be opened while offline. Once a PDF document is tied to a policy server and a specific policy, that policy can be changed or revoked by the owner. This controls documents that are otherwise “in the wild.” Each document open and close event can also be tracked by the policy server. Policy servers can be set up privately or Adobe offers a public service through Adobe Online Services. As with other forms of DRM, adherence to these policies and restrictions may or may not be enforced by the reader software being used.

SysInfoTools PDF Repair software recovers data from corrupt PDF files and it can repair multiple PDF files at a time.

SysInfoTools PDF Manager software is to deal with PDF files. This software can split large PDF files into small number of PDF files, protect PDF files by applying password to save PDF files from unauthorized users, remove restrictions like copying, printing editing  and can merge small number of PDF files into single PDF file.

What is structure of Zip file?

July 5th, 2011 admin

The name “zip” (meaning “speed”) file is sometimes called an “archive” file. The Zip file itself is really just a container… it holds the real files inside it. The purpose behind the Zip file is transportation and storage. The Zip file acts like a Ziploc sandwich bag – it holds contents inside for easy transporting and storage. This makes Zip files (and their counterpart Rar files) very valuable to file sharers and downloader.

‘Zipping’ and ‘unzipping’ is a file management technique for packagi

ng multiple files into a single small bundle. Zipping and unzipping are very popular for emailing file attachments, downloading, and FTP.

The ZIP formats a  data compression and archive format. A ZIP fil

e contains one or more files that have been compressed, to reduce file size, or stored as is. The ZIP file format permits a number of compression algorithms.

ZIP files generally use the file extens

ions “.zip”  or  ”.ZIP”

File types that are reduced the most as a result of zipping are text-oriented file types, such as .txt, .doc, .xls, and graphics files that use non-compressed file types such as .bmp. Some graphic files, such as .jpg and .gif files, already use compression; therefore, the file size is reduced very little by zipping. Also, a Word document that is full of graphics files does not get reduced as much as a document that is mostly text.

Technical information

ZIP is a simple archive format that stores multiple files. Compression is optional in a zip archive, and if it is used, it is applied on a per-file basis.

The ZIP format uses a 32-bit CRC algorithm and includes two copies

of the directory structure of the archive to provide greater protection against data loss.

How Do Zip Files Work?

A Zip file achieves three things:

  1. It bundles one or more files into a single container file.
  2. It compresses (archives) its contents to be as much as 90% smaller size.
  3. It can provide an optional password padlock on its contents.

Is ‘Zip’ the same as ‘WinZip’?

Although many people confuse the two, they are technically different.

  1. “Zip” is the generic file format of a compressed archive.
  2. “WinZip”, like “WinRAR” or “PKZip” is specialty software that creates and manages Zip files.

Structure

A ZIP file is identified by the presence of a central directory which is located at the end of the structure in order to allow the appending of new files. The central directory stores a list of the names of the entries (files or directories) stored in the ZIP file, along with other metadata about the entry, and an offset into the ZIP file, pointing to the actual entry data. This allows a file listing of the archive to be performed rel

atively quickly, as the entire archive does not have to be read to see the list of files. The entries in the ZIP file also include this information for redundancy.

The order of the file entries in the directory need not coincide with the order of file entries in the archive.

Each entry is introduced by a local header with information abo

ut the file such as the comment, file size and file name, followed by optional “Extra” data fields, and then the possibly compressed, possibly encrypted file data. The “Extra” data fields are the key to the extensibility of the ZIP format. “Extra” fields are exploited to support the ZIP64 format, WinZip-compatible AES encryption, file attributes, and higher-resolution NTFS or Unix file timestamps. Other extensions are possible via the “Extra” field. ZIP tools are required by the specification to ignore Extra fields they do not recognize.



The ZIP format uses specific 4-byte “signatures” to denote the various structures in the file. Each file entry is marked by a specific signature. The beginning of the central directory is indicated with a different signature, and each entry in the central directory is marked with yet another particular 4-byte signature.

There is no BOF or EOF marker in the ZIP specification. Often the first thing in a ZIP file is a ZIP entry, which can be identified easily by its signature. But it is not necessarily the case that a ZIP file begins with a ZIP entry, and is not required by the ZIP specification.

Tools that correctly read ZIP archives must scan for the signatures of the various fields, the ZIP central directory. They must NOT scan for entries because only the directory specifies where a file chunk starts. Scanning could lead to false positives, as the format allows for other data to be between chunks.

The ZIP specification also supports spreading archives across multiple file system files. Originally intended for storage of large zip files across multiple 1.44 MB  floppy disks this feature is now used for sending zip archives in parts over email, or over other transports or removable media.

Compress and uncompress files (zip files)

Compressed files take up less storage space and can be transferred to other computers more quickly than uncompressed files. You can work with compressed files and folders in the same way that you work with uncompressed files and folders. You can also combine several files into a single compressed folder, making it easier to share a group of files, since you only need to attach one folder to an e‑mail message instead of several files.

To Compress a file or folder
  1. Locate the file or folder that you want to compress.
  2. Right-click the file or folder, point to Send To, and then click Compressed (zipped) Folder.

A new compressed folder is created. To rename it, right-click the folder, click Rename, and then type the new name.

To Extract files or folders from a compressed folder
  1. Locate the compressed folder that you want to extract files or folders from.
  2. Do one of the following:
  • To extract a single file or folder, double-click the compressed folder to open it. Then, drag the file or folder from the compressed folder to a new location.
  • To extract the entire contents of the compressed folder, right-click the folder, click Extract All, and then follow the instructions.

ADVANTAGES OF ZIP

  • You save storage space. Zipping large files can save up to 80 percent or more in hard disk space.
  • Smaller file size drastically reduces e-mail transmission time.
  • The smaller file size of e-mail messages that you want to keep is useful when your mailbox has a space limit.
  • Many zip utilities allow you to encrypt files and protect sensitive data, especially when you send it in e-mail.
  • You can send and receive e-mail attachments, such as .exe files, that would otherwise be blocked by outlook  for security reasons.
  • Many zip utilities support disk spanning, which means when you create a .zip file on a removable disk and run out of disk space, the utility prompts you to insert additional disks as needed and then continues the process.
  • Many zip utilities allow you to create a self-extracting archive. These are archives that compress and package the files that you specify as an executable (.exe) file. When you click the executable file to open it, the .exe has the ability to extract the files from within itself and produce the original files.

LIMITATIONS OF ZIP

  • The minimum size of a ZIP file is 22 bytes.
  • The maximum size for both the archive file and the individual files inside it is 4,294,967,295 bytes (232−1 bytes)for standard ZIP, and 18,446,744,073,709,551,615 bytes (264−1 bytes) for ZIP6
  • This approach is less well-suited, in general, to archival of a large number of small files. In the ZIP archive format, the metadata for each entry—the information about each individual entry—is not compressed. This limits the maximum achievable compression ratio, especially as the size of the individual entries diminishes and approaches the size of the metadata for the entry

Sometimes zip file get corrupted and prompt error message  “The Compressed (zipped) folder is invalid or corrupted.” While opening the zip file. In this case manually you cannot repair zip file to get your lost data back.

SysInfoTools Zip Repair utility is an powerful tool which has advanced features to get data back from the corrupted zip files. This tool uses advanced algorithms to recover data from zip files.

How to manage MS-Outlook PST file?

July 5th, 2011 admin

When you use Microsoft Outlook, you need a place to keep your e-mail messages, calendar, tasks, and other items. This storage place, known as a data file, allows you to keep your data on your computer.

Personal Storage Table (.pst) is an open proprietary file format used to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook.

A Personal Folders file (.pst) is an Outlook data file that stores your messages and other items on your computer. Personal Folders files are the most common format in which information in Outlook is saved by home users or in small organizations. If you do not connect to an Exchange Server computer, your e-mail messages, Calendar, and other items are delivered to and stored on your local computer in a .pst file.

Your items can also be moved or archived to a Personal Folders file (.pst). Because a .pst file is kept on your computer, it is not subject to mailbox size limits on the mail server. By moving items to a .pst file on your computer, you can free up storage space in the mailbox on your mail server. Outlook can be configured to deliver new items to a .pst file

.pst files use a fixed-block-based allocation scheme; the file is enlarged by a fixed amount of bytes, and the file internally maintains information about the allocated and non-allocated blocks. So, when data files like email messages are added to a .pst file, its file size is automatically adjusted by the mail client (if necessary). When mail is deleted from a .pst file, the size of the .pst file will stay the same, marking the space as unallocated so that it will hold future data items. Recently removed data items can actually be recovered from .pst files

To reduce the size of .pst files, the user needs to compact them.

DATA ACCESS

Password protection can be used to protect the content of the .pst files The password to access the table is stored without the first and last XOR CRC-32 integer representation of itself  in the.pst file. Outlook checks to make sure that it matches the user-specified password and refuses to operate if there is no match. The data is readable by the libpst project code.

Microsoft (MS) offers three values for the encryption setting: none, compressible, and high.

  • No Encryption – This option does not encode your .pst file. A user may be able to read the .pst file with a text editor program or with a hexadecimal editor program.
  • Compressible Encryption – This option encodes your .pst file in a format that allows compression, but the .pst file is compressed only if you have a compression program on your computer. The .pst file cannot be read with a text editor or with a hexadecimal editor.
  • High Encryption – This option encodes your .pst file in a format that offers increased protection. If you have a disk-compression program, the .pst file can be compressed, but to a lesser degree than if you were using the Compressible Encryption option. The .pst file cannot be read with a text editor or with a hexadecimal editor.

Note that neither of the two encryption modes uses the user-specified password as any part of the key for the encryption.

We recommend that you regularly back up your .pst files and store them in a safe place. Your ISP or Microsoft cannot recover your e-mail or other items if the .pst file is lost.

SUPPORT

As with any file, .pst files can become corrupted. Prior to Outlook 2003, the default .pst file format was ANSI and had a maximum size of 2 GB. If the .pst file were allowed to grow over 2 GB, the file would become unusable. Microsoft provides PST2GB a tool that can be used to truncate a .pst file that has grown over 2 GB. Microsoft also provides scanpst.exe that can be used to repair other .pst file-corruption issues. In Outlook 2003 and later, .pst files are created in the Unicode format (Unicode: A character encoding standard developed by the Unicode Consortium. By using more than one byte to represent each character, Unicode enables almost all of the written languages in the world to be represented by using a single character set.) and have a default maximum size of 20 GB.

A file that is created in the Outlook Personal Folders file (.pst) format in Outlook 2003 or Microsoft Office Outlook 2007 is not compatible with earlier versions of Microsoft Outlook and cannot be opened by using those versions. To create a data file that is compatible with Outlook 2002 and earlier versions, you can create data files in the Outlook 97-2002 Personal Folders file (.pst) format. This file format is the same as the format that was available in earlier versions of Outlook.

When you copy a .pst file from a CD-ROM, from a CD-R, or from a CD-RW, make sure that the file attributes for the .pst file are changed from Read Only to Archive before you start Outlook. When you delete items from your Personal Folders in Outlook, the .pst file size does not decrease automatically. The file must be compacted to reduce the file size. Outlook wil compact the .pst file in the background during idle time.

CREATION OF .pst  FILE

Create a new .pst file while Outlook is running

To create a .pst file while Outlook is running, follow these steps:

  1. On the File menu, point to New, and then click Outlook Data File.
  2. In the Types of storage area, click Office Outlook Personal Folders File (.pst) to create a new Outlook 2003 .pst file. Click Outlook 97-2002 Personal Folders File (.pst) to create a new Outlook .pst file that is compatible with earlier versions of Outlook.
  3. Click OK.
  4. Use the default Outlook folder location, or you can locate a different folder location.
  5. In the File name box, type a name for the new .pst file, or you can use the default name. Click OK.
  6. In the Name box, type a title for the .pst file, or you can use the default title of Personal Folders. The title that you enter in the Name box is the name that is used on the Outlook 2003 All Mail Folders list, and it is applied to any shortcuts that are made for the .pst file on the Outlook Bar. You can also select an encryption setting and a password for the .pst file. After you select the settings that you want, click OK.Note you cannot change the encryption setting after you create the .pst file.
  7. The new .pst file is added to the Outlook 2003 All Mail Folders list. To view the Folder List, click Folder List on the Go menu.

Create a new .pst file with the Tools menu

To create a new .pst file with the Tools menu, follow these steps:

  1. On the Tools menu, click E-Mail Accounts.
  2. Click View or change existing e-mail accounts, and then click Next.
  3. In the E-Mail Accounts dialog box, click New Outlook Data File.
  4. In the Types of storage area, click Office Outlook Personal Folders File (.pst) to create a new Outlook 2003 .pst file. Click Outlook 97-2002 Personal Folders File (.pst) to create a new Outlook .pst file that is compatible with earlier versions of Outlook.
  5. Click OK.
  6. Use the default Outlook folder location, you can locate a different folder location.
  7. In the File name box, type a name for the new .pst file, or you can use the default name. Click OK.

In the Name box, type a title for the .pst file, or you can use the default title of Personal Folders. The title that you enter in the Name box is the name that is used on the Outlook 2003 All Mail Folders list, and it is applied to any shortcuts that are made for the .pst file on the Outlook Bar. You can also select an encryption setting and a password for the .pst file. After you select the settings that you want, click OK.

How to access the secured NSF files of Lotus Notes

July 29th, 2010 admin

Lotus Notes is one of the most popular email client used in small and big organizations. Lotus notes save all its emails in NSF files. Lotus Notes has an attribute named as Access Control List (ACL) using which administrator set access rights to particular NSF file. Using this attribute file owner manages the NSF file and applies security on NSF files so that unauthorized user cannot access the file. If an error message like
You are not authorized to access that database.
You are not authorized to perform that operation in Lotus Notes.
are flashed every time when you try to access NSF file, this is only because you are not authorized to access that particular NSF file, there is strong security applied to the database file by its author or  administrator. This is basically done to avoid any hampering of NSF files or restricting any unauthorized usage of file. The administrator has the only rights to deal with file not anyone else.
Therefore when any other user tries to access that particular NSF files the aforementioned errors are flashed.

Sometimes situation may arise that you urgently need to access protected NSF file. And every time you access the file the above mentioned errors are flashed. The only solution to these types error messages is to contact the administrator and ask him to provide the access rights.  But if the administrator is absent or not available and accessing of protected NSF file is important then the only solution is to use third party tool knows as NSF local security remover. This tool will help you to deal with above mentioned errors and provide access of protected NSF files.

This tool quickly removes the local security of NSF file and provides instant access of the protected NSF files. No technical skills are required to use this tool.

Repair Of PDF files after disk crash

July 22nd, 2010 admin

PDF file format is a proprietary file format developed by ADOBE Systems for the purpose of document exchange and printing. PDF document describe a document whether it is 2D or 3D in a hardware, Operating system and Application independent environment this comprised description of each and every element of the document in a well formatted and well documented language. PDF is now the industry standard for the intermediate representation of printed material in electronic prepress systems for conventional printing applications. Benefits of PDF files are as follows:

Preservation of document integrity across the enterprise, independently of the
Device, platform, and software

It helps Merging of varied type of content from diverse sources like Web sites, word processor and spreadsheet programs, scanned documents, photos, images and graphics into one self-contained document while maintaining the integrity of all original sources and content.

It helps collaborative editing of documents from multiple locations or platforms.

It provides support to Digital signatures to certify authenticity

It includes Security and permissions to allow the creator of the document to retain control of the document so that writer can retain its rights.

It integrates Accessibility features of content to those readers with disabilities

Well documented file format support Extraction and reuse of content using other file formats and applications.

Each and every element of document is named as OBJECT in PDF and provided a number to them. Every object can be a parent of other objects so in this way a page object can have various object of content object like image and text. Layout, color and fonts are various attributes which can be abide to the object.

So in this manner PDF documents are very helpful but their file formats are from very simple to rather complex. PDF documents are used very much for archiving purpose and if any PDF file get corrupted due to file system or underlying media corruption then there chances that users can loose all the data associated with that. PDF file are plain text file but despite this fact they are completely unreadable if one see them directly. In such cases repair process become very complex and interpretation of data scavenged become very hard to assimilate. It becomes like jigsaw puzzle. To prevent that user must take following measures.

What to do when Outlook Express gets crash or corrupted due to any fault?

July 22nd, 2010 admin

Outlook Express is a default email program for Windows XP family of operating systems. Outlook Express is an e-mail and news client which is included with Internet Explorer from versions 4.0 through version 6.0. Outlook express is most widely used e-mail client because it is being served by the Microsoft for free with operating system or internet explorer. Microsoft outlook express is a default manager for window address book also.

Despite of heavy dependency and wider user base this software is not untouched by the possibilities of corruption in database as slight corruption if one of its dependents data file can left outlook express totally unusable or inoperable. In most cases frustrated and fearful users who feared for loss of data can move to some dirty data recovery companies who charge a lot for even a miss-configuration as user is not aware of the perfect configuration or might charged heavily for the recovery of data which is not relevant as data recovery perspective as main data remains intact and they just recover Folder.dbx file which contains all the hierarchy of the mails. It is not even required for Outlook express to work properly. So in this case what a user should do?

Here in this article I will try to elaborate you some common problems related to outlook express and their solution so that you do not have be fearful in cases when outlook express is showing errors like these.

“This program has performed an illegal operation and will be shut down.
If the problem persists, contact the program vendor.”
MSIMN caused an invalid page fault in module Msoe.dll at address 0x800c015e
“Outlook Express could not be started. It may not be installed correctly. Make sure that your disk is not full or that you are not out of memory. Contact Microsoft support for further assistance. (0x800c012e)
Outlook Express could not be started because Msoe.dll could not be initialized. Outlook Express may not be installed correctly.”
“Folder could not be displayed. Outlook express could not open this folder.
Possible causes are: Low disk space or Low memory.”
Msimn caused an exception C0000006h in module Directdb.dll. The message could not be sent. There is not enough Disk space.
Unknown error has occurred. Protocol: SMTP Port: 0 Secure: No [SSL] Error: 0x800c0131
MSIMN caused an invalid page fault in module Msoe.dll
Outlook Express could not be started because Msoe.dll could not be initialized. Outlook Express may not be installed correctly.

Well these are some errors which you can see over the time you work on Outlook Express. Some of those errors are trivial to solve and some are not so trivial and rest are impossible as data recovery will become inevitable on some cases. Instead of solving every problem individually I will tell you a list of steps which you can follow as a overall maintenance of the Outlook Express. After this I will give you some tips-n-tricks to overcome or solve some errors. So the steps are:

1.Clear you’re Temporary Internet Files. As outlook use Internet Explorer internally.
2.Compact Your Folders of Outlook Express. How?  Go to Tools>Options>maintenance>Clean up Now >Compact. It’s easy. But make sure that you put your status offline so that no new message arrives during compaction as it will confuse Outlook Express.
3.Re-Register Microsoft Outlook. Start>Run> type “msimn /reg”.
4.Re-Register these necessary dlls.
Start>run>type”cmd” now type these lines but once at a time
regsvr32 msjava.dll   press ENTER
regsvr32 shdocvw.dll   press ENTER
regsvr32 browseui.dll   press ENTER
regsvr32 mshtml.dll   press ENTER
5.Delete Folder.dbx. If any serious errors occur does this as Folder.dbx maintain only tree structures of folders. Corrupt Folder.dbx will hang Outlook Express but absence of it will force Outlook Express to re-index all mails or messages.
6.Disable e-mail scan in anti-virus program.
7.Disable background compaction.
8.Took Back-Up Regularly.
9.Last but not least. Keep DBX repair software in advance just for emergency.

DBX file repair is a best tool to handle such situation and it can recover almost all mails from your DBX file. DBX repair is the best tool available in the market for the purpose of repairing DBX files.

Restoring BKF Files In Case Of Missing Catalog Files

July 13th, 2010 admin

A backup or the process of backing up refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. Backup is the most important step to prevent data loss. Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Data loss is also very common. 66% of internet users have suffered from serious data loss.

Since a backup system contains at least one copy of all data worth saving, the data storage requirements are considerable. Organizing this storage space and managing the backup process is a complicated undertaking. A data repository model can be used to provide structure to the storage. In the modern era of computing there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.

Backing up of important data files in computer is a prime requisite these days with the ever increasing dependence on computers and with the increasing importance of computer based data in almost every type of work.

Users of Microsoft Windows have given in-built software for the backup of all the data. This process is quite useful and helpful in safeguarding the important data saved in the system. These MS backup files are created using the tool called NTBackup.

NTBackup is the built-in backup application to create a proprietary backup format (BKF) (also known as “Microsoft Tape Format” or MTF) to back up files. Files can be backed up to tape, ZIP drives, floppy disks, and hard drives. NTBackup supports Encrypting File System, NTFS hard links and junction points, alternate data streams, disk quota information, mounted drive and remote storage information. It saves NTFS permissions, audit entries and ownership settings, respects the archive bit attribute on files and folders and can create differential and incremental backups, backup catalogs, as well as Automated System Recovery.

This utility is not fault-proof as it also get corrupted due to some unavoidable reasons like virus, improper system shutdown, power failure, etc. Sometimes, NTBackup corruption happens due to missing catalog files. In such situations, you may not be able to use the BKF file to restore your data at the time of data loss. Thus, in situations, you would be required to repair bkf file to retrieve and restore your data.

During the backup operation, catalog files are created and stored in the catalog folder on the system these appear under the NTBackup Restore tab. When you try to create more than one backup at the same time, these files share matching timestamp attribute. The backup set that was created first, is depicted in the Restore tab, but the other backups does not appear in the Restore tab. Such situations cause BKF file corruption.

BKF Recovery is the process of repairing and restoring damaged BKF file. This is potential through powerful and advanced third party tools that allow you to easily Repair BKF File.

SysInfoTools BKF repair is the fastest and efficient tool to recover BKF file in most of the cases. It works with BKF files created using NTBackup tool of Windows 2003, XP and 2000 and also the files created using Backup Exec by VERITAS software. It is compatible with Windows Vista/2003/XP/2000.

Outlook does not recognize PST Password once System Crash

July 8th, 2010 admin

A Personal Storage Table (or Personal Folders file) is the data file used to store all your messages, calendar events, and other items in Microsoft Outlook and other Microsoft software (Exchange Client, Windows Messaging). PST format is mostly used in home users or in small organizations. As all the data of Microsoft Outlook is stored in one . PST file on the local computer, you can easily backup or sync your mails.

The .PST format has been increased greatly since the Microsoft Outlook 2003 that provides greater storage capacity (maximum file size 20GB) and Unicode support.
PST files are extremely important for your mails. It’s necessary to apply protection on them. However, password protection of PST files is not so secure technically, since there have been tools that can remove or bypass the password protection. Password protection can be used to protect the content of the .PST files.

PST stores the 32 bit CRC32 hash value of the password entered by the user. When a PST file is opened using any version of Outlook it’ll check the hash value stored in it. If this hash value is 0 the file will be opened without any password requirements. If it found any other value the enter password dialog will pop up. The problem with CRC32 hash is the fact that a lot of strings can have the same CRC32 hash.  This means for a single 32 bit hash value there will be a lot of different but correct passwords! But sometimes, you may watch that Outlook fails to identify the PST password. It generally happens because of two possible reasons: PST password is not correct or is damaged.

The .pst file format is fundamentally insecure for multiple reasons. First, the password (actually a weak (without the first and last XOR) CRC-32 integer representation of it) is simply stored in the .pst file, and Outlook checks to make sure that it matches the user-specified password and refuses to operate if there is no match. But the actual data is still there.

Second, Microsoft (MS) offers three values for the encryption setting: none, compressible, and high. None encryption is easy because the .pst file contains data in plaintext, and a simple text editor will show the contents.
Compressible encryption is a simple byte-substitution cipher with a fixed substitution table. Of course, since the table is fixed, it is also widely known. Attackers can simply decipher the data and see the computer’s plaintext.
High (sometimes called “better”) encryption is similar to a WWII German Enigma cipher with three fixed rotors, which are widely known. If the key, which is the value of an internal identifier, is known, attackers can simply decipher the data and see the computer’s plaintext.
In all such cases, PST Password Recovery tools come to solve the problem.

PST Password Recovery tools are user friendly graphical interface and equipped with superior options. This software is designed with proper Outlook Password Recovery techniques and safe algorithms. All the techniques are safe and non-destructive to maintain complete data integrity.

PST Password Recovery Software is the best utility to recover lost PST file password. It can recover PST Password for files created with Outlook 2007, 2003, 2002 and 2000. It is compatible with Windows Vista, XP, 2003 and 2000.

Outlook Express Hangs Due To Virus Attack

July 7th, 2010 admin

One of the main reasons for loss of emails in Outlook Express has been found to be due to virus attacks. These viruses can affect the email client, resulting in permanent loss of all your private and confidential emails. A virus received in an Outlook Express e-mail can only spread its infection when you open the associated attachment. Each time, when you try to open Outlook Express, it comes with ‘Not Responding’ status with two options to ‘End Now’ or ‘cancel’. Click ‘End Now’ button exits from Outlook Express.

Viruses can involve Outlook Express in several ways:

A user opens a virus-infected attachment received via an Outlook express e-mail message. Because this is the most common way viruses spread, many system administrators block certain attachments at the server or use the Outlook express Email Security Update to block such attachments at the client.

Messages exploiting certain vulnerabilities in HTML mail can force a malicious file attachment to run even if the user only views it in the preview pane or opens the message. Getting the latest patches for Internet Explorer provides protection.

Because of Outlook’s express easy-to-use programming model, viruses can propagate themselves by reading the Outlook express address books and sending new virus-infected messages to everyone found there. However, virus developers seem to be aware of the new security provisions in Outlook express, because the latest viruses have included their own SMTP engine to send messages, thus avoiding Outlook’s express security prompts.

Such problems occur when you have not installed any anti-virus software to prevent against viruses. Trojan alert indicate that only a Firewall has been installed.

To protect your machine from becoming infected with a virus received via Outlook express, you should:
 Practice good anti-virus safety
 Tighten e-mail attachment security
 Update Outlook Express, Internet Explorer, and other Windows components

 Install the latest service packs and updates for your version of Outlook express.

To Recover DBX files by repairing the folder, you need to take the help from the third party tool.

Outlook Express Recovery software is the best utility that scans and repairs corrupt DBX file(s) created with Outlook Express. This DBX Repair software can repair or restore DBX file using the most effective plus safe scanning algorithms. The utility extracts the lost e-mails as .dbx and .eml file(s).
