Consider a similar situation in which you are unable to mount the database on MS Exchange Server 2007. The following error message is displayed:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724
Exchange System Manager”

In addition, when you check the error log the following event is logged:

“Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 486
Description: Information Store (3932) First Storage Group: An attempt to move the file “E:\Program Files\Exchsrvr\mdbdata\E00.log” to “E:\Program Files\Exchsrvr\mdbdata\E000080A.log” failed with system error 2 (0×00000002): “The system cannot find the file specified.” The move file operation will fail with error -1811 (0xfffff8ed).”

Cause:

You may have run the eseutil /p command on the damaged databases. This problem has occurred because the transaction log files were not removed during the process.

Resolution:

First of all, you should check whether eseutil was run on this system at all or not by performing the following steps:
1.Click Start | Run.
2.Enter ‘CMD’ in the ‘Run’ box and press ‘Enter’ key. The Command Prompt window will be displayed.
3.Enter the following command:
4.c:\program files\exchsrvr\bin\eseutil /mh “c:\program files\exchsrvr\mdbdata\name of Exchange database.edb”
5.Check the repair count field. If it is 0, then the eseutil /p command was not run. For a non-zero count, eseutil /p command was run on the database.
Now, you can transfer the transaction log files to another folder if the database is in a clean shutdown state. To check this condition, you should perform the following steps:
1.Click Start | Run and enter ‘cmd’ in the ‘Open’ box and click OK.
2.To check the private information store, enter the following command in the Command Prompt:
3.c:\program files\exchsrvr\bin>eseutil /mh “drive:\program files\exchsrvr\mdbdata\priv1.edb”
4.To check the public information store, enter the following command in the Command Prompt:
5.c:\program files\exchsrvr\bin>eseutil /mh “drive:\program files\exchsrvr\mdbdata\pub1.edb”
6.Analyze the consistency check results. If the database is consistent, then all the transaction log files are moved to the information store.
7.Transfer all the log files from the directories to a backup folder.
8.Now try to mount the database. It should run fine now.

In the event of still unable to mount the database, the only way of resolving this problem is to use a third-party MS Exchange repair software. These tools are highly interactive in nature that do not damage the EDB files while scanning them.

The best Exchange repair software among all the available tools is Stellar Phoenix Exchange Server Recovery that repairs corrupted EDB files integrated in MS Exchange Server 5.5, 2000, 2003, and 2007.

“A Transport database operation has encountered a fatal error. The database may be corrupted. The Microsoft Exchange Transport service is shutting down. Manual database recovery or repair may be required.”

After the above error, Microsoft Server does not let you access your database. At this point, you have to verify the cause of this problem and perform Exchange repair by resolving it.

Cause:
The root cause of this erroneous situation is that the specified database in the error message is damaged, which is causing the MS Exchange database services to mount it.

Resolution:

To resolve this problem, you should perform either of the following methods:

1. Delete the database: You should delete the database in question along with the respective transaction logs. After the deletion, a new copy of the database with the transaction logs will be created automatically. However, you would not get the previous data in this case.

2. Repair the database: You should try to repair the database using the Eseutil /P utility on the corrupted database. After the database repair, restart the MS Exchange Transport service to ascertain whether the error has been resolved or not.

However, if the problem is still not resolved then you should use a third-party Exchange Server repair software to do the needful for you. Such Exchange repair tools are read-only in nature that possess fast yet sophisticated scanning algorithms to extract the EDB files in the form of distinct PST files.

Stellar Phoenix Mailbox Exchange Recovery is an MS Exchange repair software that is able to repair corrupted EDB files from all instances of logical corruption. It is specially designed to perform Exchange repair on MS Exchange Server 5.5, 2000, 2003, and 2007. This Exchange repair software is able to extract the EDB file into separate PST files for each user. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Consider a scenario, wherein, you, being the administrator, try to mount the mailbox store in Exchange System Manager, and receive the following error message:

“Unable to Mount the Mailbox Store with error c104173c The Information Store is Busy”

Cause

The above error indicates the possible corruption in one or both edb files (Priv1.edb or Pub1.edb) of information store.

Resolution

In order to troubleshoot the issue, you must perform the following Exchange Repair steps:

1. Run eseutil/mh command in order to determine if the database is consistent
2. If you get the following output ‘Clean Shutdown’ , move out all the log files from Exchsvrmbddata folder
3. But if you get ‘Dirty Shutdown’ as output, perform soft recovery by using eseutil/r
4. If database does not come to a consistent state, perform hard repair by using eseutil/p command.
5. If you use the above command, you may lose some Exchange Server data, including the messages that were contained in the log files that were not committed to the information store database. Therefore, it is a wise decision to use a third-party MS Exchange Repair application.

Such tools repair corrupt .edb files safely and employ improved scanning algorithms to recover inaccessible data in a hassle-free manner. Being-read only they do not modify the original content. Therefore, you can use them blindly and isolate the information store corruption issues efficiently.

Stellar Phoenix Mailbox Exchange Recovery is a powerful and reliable application which repairs corrupt .edb files and restores the mailboxes as individual PSTs. Compatible with Exchange Server 5.5, 2000, 2003, and 2007, this Exchange repair software recovers all e-mail messages, notes, journals, tasks, contacts and other components.

Consider a case when you try to start Information Store service of Exchange Server and it doesn’t proceed as expected. In addition, you receive the below mentioned error message in system log or on screen:

“The Microsoft Exchange Information Store service terminated with service-specific error 4294966277.”

On examining the issue, when you view the Application Event log, the following entry is observed:

Event ID: 0
Source: ESE97
Type: Error
Category: Logging/Recovery

Description: MSExchangeIS ((451)) -1019

Event ID: 1120
Source: MSExchangeIS
Type Error
Category: General

Description: Error 0xfffffc05 initializing the Microsoft Exchange Server Information Store database.

The above symptoms indicate database corruption and thus when you run Eseutil repair utility, the following message is received:

“-1019 0xFFFFFC05 JET_errPageNotInitialized Repair Only: Read an unused page 4294966277”

Consequently, the corrupted database cannot be repaired.

Explanation

JET_errPageNotInitialized error typically indicates a blank page. But, if it occurs when starting the information store, this shows database page corruption. There can be several pages that cannot be initialized. So, Eseutil cannot repair this database.

User Action

Before troubleshooting the issue, you should determine the cause of the error. Generally, these problems are persistent and occur because of failing hardware. Implement the following actions to solve the problem:

Disable all anti-virus applications, file backup programs, and low-level access utilities
Run hardware diagnostics and check system log for hardware-related issues
Restore the database from your previous backup

At times, database backup is not available or exist in invalid state. In such situations, you should use an Exchange Repair Software. Designed to run powerful, yet safe, scanning algorithms, these utilities are competent to restore Exchange database contents, irrespective of the nature of corruption. Also, MS Exchange Repair utilities are easily operable because of their user-friendly design.

Supporting MS Exchange Server 2007, 2003, 2000, and 5.5, this Exchange Server Repair tool facilitates you to restore only the required mailboxes. In addition, it can also recover deleted mailboxes.

To elaborate the above situation, consider a real-time scenario wherein you have a MS Exchange database of around 300 GB. The database (priv.edb file) gets corrupted and you also fail to roll back. To resolve file corruption, you run ‘eseutil/p’ utility. The repair process was successfully repairing the file, until it stopped and displayed the below error message:

“Assertion Failed: dPercentage >=0, file G:\ese97\src\eseutil\edbutil.cxx, line 563.”

After the above error message flashes on the screen, the repair process stops, resulting in complete inaccessibility of MS Exchange database. Additionally, the same error message appears every time you use ‘eseutil/p’ utility to repair the database.

Cause:

The root cause for ‘eseutil/p’ utility failure is severe corruption in priv.edb file.

Resolution:

To get past the above error message and to overcome ‘eseutil/p’ utility failure, you will need to follow the below mentioned steps:

1. Use a complete and valid backup to perform restoration of the database.

2. However, in situations where no backup exists or backup falls short in restoring required data, you will need to use a commercial Exchange Server Repair application. Such Exchange Server Repair tools use safe mechanism for repairing the database to maximum possible level. These tools can be used by any computer user, irrespective of its understanding about database repair.

“Could not start Microsoft Information Service on local
computer, Error 1053: The service did not respond to the start or control
request in a timely fashion”

After the above error message pops up on the screen, the data saved in the Information Store becomes inaccessible.

Cause:

The above error message flashes only when the Information Store gets corrupted due to unexpected system shutdown, header damage, anti-virus scan, log file corruption, or virus attack.

Resolution:

To get past the above error message and to access the records saved in the Information Store, follow the below guidelines:

1. Repair the corrupted .edb file using an ‘eseutil/p’ inbuilt repair command.
2. If the command fails to repair, then restore the file from an updated backup.
3. If backup file is unavailable or corrupted, then use a third-party Exchange Server Repair application to repair the file. Such Exchange Repair applications use effective repair mechanisms to repair any logically damaged MS Exchange database.

Compatible with Windows 7, Vista, XP, 2003, and 2000, the user-friendly application is easy-to-operate, and doesn’t require any prior technical knowledge to operate.

To illustrate the above situation, consider a practical case wherein your Exchange database gets corrupted and the server stops the recovery of the database:

“Error -1216 (JET_errAttachedDatabaseMismatch) ”

On viewing the event log, you encounter the underneath entry:

“Event Type: Error
Event Source: ESE98
Event Category: Logging/Recovery
Event ID: 0
Date: 4/24/2001
Time: 6:20:18 PM
User: N/A
Computer: EXCHANGE1
Description: Information Store (4312) Database recovery failed with error -1216 because it encountered references to a database, ‘D:\exchsrvr\mdbdata\PRIV2.edb’, which is no longer present. The database was not brought to a consistent state before it was removed (or possibly moved or renamed)”

Cause:

The root cause for the occurrence of the above error message is replacement or deletion of critical files that are used to open and operate Exchange Server database.

Resolution:

To resolve the above error message and to access Exchange Server database, you will need to follow the below mentioned steps:

• Use Eseutil/P repair command to repair the database.
• If the command fails, restore the database from an adequate backup.
• In case of backup unavailability, use a commercial Exchange Server Repair application. An Exchange Repair utility ensures maximum edb repair of logically damaged MS Exchange database and restoration at user-specified location.

Exchange Repair Software is a powerful, yet easy to operate Exchange Repair application that is competent enough to repair any Exchange Server 5.5, 2000, 2003, and 2007 databases. The repair application recovers almost all EDB file objects, including e-mails, tasks, notes, attachments, and appointments. It can be installed on Windows 7, Vista, XP, 2003, and 2000.

For detailed explanation of the above problem, consider a practical case wherein your Exchange Server database gets corrupted. And, when you try to repair the database using Eseutil/p utility, you encounter:

“Operation terminated with error -1605 (JET_errKeyDuplicate, Illegal duplicate key) after xxx.xxx seconds.”

Data saved in the database becomes inaccessible after the above error message appears. Additionally, the same error message repeatedly occurs when you try to repair your database.

Cause:

The fundamental reason for the occurrence of the above error message is that the repair utility might rebuild B-trees incorrectly. This will change the complete metadata structure of the database, leaving it in a permanently non-repairable state.

Resolution:

To resolve the above error message and to access the records saved in the database, a user needs to obtain the latest service pack of MS Exchange Server 5.5 and perform repair. However, if the repair utility is unable to repair the database even after installing the service pack, then you need to opt for an advanced commercial Exchange Server Repair application.

If this  condition persists then please restore the database from a previous backup.”

Cause:

As described in the error message, Exchange database is corrupt.

Resolution:

To overcome the above error message:

1. Uninstall all the anti-viruses and third-party software.

2. Use a previous online backup to restore the information store.

3. Move all the mailboxes in database to a new server or mailbox store.

4. In case all the above measures fail to resolve your problem, you will have to repair the database using eseutil/p command.

‘ from a call to ‘HrESEBackupClose()’ additional data ‘-’

Apart from the above event ID, other entries are event ID 217, 478, 215, and 222.

Cause

The above symptoms is most probably the outcome of Exchange database corruption that doesn’t allow you to backup the database.

Solution

In case of Exchange Database corruption, you can try solutions as given below:

• If you use Enterprise edition of Exchange Server, you can move all the mailboxes from corrupted store to a new one.

• In other cases, the best solution is to restore the database from backup and to replay the log files

• If you don’t have a suitable backup to restore, you can run eseutil /p repair utility to fix database corruption. Keep in mind to backup all the data prior to running this tool as chances are that your important data may get deleted.

• In case, none of the above methods works, you should opt for a third-party MS Exchange Repair utility. An Exchange Server Repair utility can run most effective and safe scanning algorithms to extract all user data from corrupted Exchange databases.

Cause:

The above error message pops up only when the Private Information Store or your Exchange Server gets corrupted/damaged.

Resolution:

Below are some techniques that help you in resolving the above error message:

• Execute ESEUTIL/D command to defragment your database. This enables you to resolve minor corruption problems in your database.

• If the problem persists, then restore the database from a valid backup.

• If no backup is available, then you need to use a third-party Exchange Server Repair tool to repair your database. These Exchange Repair utilities can be used after any type of logical corruption situation.

MS Exchange Repair is a safe repair application that repairs databases without modifying or overwriting any data. The Exchange Repair tool is easy to understand and restores the recovered user mailboxes in individual PST files. Compatible with Exchange Server 5.5, 2000, 2003, and 2007, the tool supports Windows 7, Vista, XP, 2003 and 2000.

For instance, consider a situation when an Exchange Server administrator, runs a backup program to take backup of a storage group. The backup task fails and the below error message pops up:

“Error, Unable to open \ because it is currently being backed up by another process.”

The error statement further suggests that database or database element is corrupt and does not let you backup the storage group.

Cause

The error indicates that Exchange storage group is in use by some other application or process. This can occur due to one of the following reasons:

1. Another backup program is simultaneously trying to backup the Exchange Information store. Since the database file(s) are open, the backup application take them as corrupted.

2. An antivirus application has been configured that is scanning the Exchange database files

3. You are using a backup utility that is not Exchange-aware

4. The Exchange database is corrupt and backup utility cannot read it

Solution

Following are the corresponding solutions that can help you recover from such problems:

1. Deselect the Exchange Server components, that are to be backed up by another backup utility running on the computer

2. Disable the antivirus program to scan Exchange Server files

3. Try using a different, Exchange-aware utility

4. Restore the problem Exchange database using the last available backup or repair it using Eseutil commands.

Running Eseutil commands for corrupted Exchange database is not safe as the resultant database can be out of some important data. For safe MS Exchange Repair, it is however, recommended to use a commercial application. These Exchange Repair software can scan and restore the affected database without harming the original integrity of database.
