SYMPTOMS
The Microsoft Exchange Information Store service on your Microsoft Exchange Server 5.5 computer may stop running. When you try to restart the Information Store service, you receive an error message that is similar to the following:

4294967041

If you use the eseutil /mh command to obtain information about the databases, the Eseutil utility reports that the databases are in an inconsistent state. Additionally, if you run the eseutil /r command, you receive an error that is similar to the following:

-255 : JET_errDatabaseBufferDependenciesCorrupted



CAUSE
This issue may occur if the Exchange 5.5 computer is shut down suddenly. For example, this issue might occur if the computer is shut down suddenly because of a power outage.

When data is saved to the Information Store database, the Extensible Storage Engine (ESE) writes transactions to the database files in three steps. If the Exchange 5.5 computer is shut down suddenly during the three-step process, links to the data that is stored in the memory buffers may be lost. If the links are lost, the buffer dependencies may be corrupted. When you try to restart the Information Store service, you receive the following ESE decimal error:

4294967041

This decimal error is the same as the following ESE error message:

JET_errDatabaseBufferDependenciesCorrupted



RESOLUTION
To resolve this issue, use one of the following two procedures.

Restore the Information Store from a backup
For additional information about how to restore the Information Store from a backup, click the following article number to view the article in the Microsoft Knowledge Base:

296229 XADM: How to recover a whole Exchange Server 5.5 computer using an online backup

Important It is always best to restore from a backup whenever possible.

Repair the database
You can use the Eseutil utility to repair the private information store (Priv.edb) and the public information store (Pub.edb).

Note Only use the eseutil /p command that is listed in step 3 as a last resort. This utility parameter forces a hard repair on the database. For more information about how to use the Eseutil utility to repair the database, click the following article number to view the article in the Microsoft Knowledge Base:

259851 Ramifications of running the eseutil /p or edbutil /d /r command in Exchange

To repair the database, follow these steps:  Click Start, click Run, type cmd in the Open box, and then click OK. Type each of the following commands, and then press ENTER after each command:

cd c:\exchsrvr\mdbdata\

eseutil /r /ispriv

eseutil /r /ispub  If the eseutil /r /ispriv command and the eseutil /r /ispub command do not complete successfully, and you receive the errors that are described in the &quot;Symptoms&quot; section, you can use the eseutil /p priv.edb command and the eseutil /p pub.edb command.

Note To run the eseutil command with the /p parameter, you must have free space on your hard disk that is at minimum 25 percent the size of the database. Typically, this procedure runs at the rate of three to six gigabytes of data per hour. When both databases are repaired, type the following two commands, and then press ENTER after each command to run an offline defragmentation of the database:

eseutil /d priv.edb

eseutil /d pub.edb

Note To run an offline defragmentation, you must have free space that is at minimum 110 percent the size of the database on the same hard disk that contains the database.

For additional information about what you can do if you do not have sufficient free space on the hard disk that contains the database, click the following article number to view the article in the Microsoft Knowledge Base:

255035 XADM: How to recover hard disk space from Exchange Server databases

 When the offline defragmentation is complete, type the following commands, and then press ENTER after each command to correct any logical schema errors that may exist:

cd\exchsrvr\bin

isinteg -pri -fix -test alltests

isinteg -pub -fix -test alltests
