SYMPTOMS

When you use the NTBACKUP tool to perform a full backup for Microsoft Exchange Server 2003 mailbox stores or storage groups, you may set the specific target location to disk or other media. If the target location is not available for some reason, the backup stops as expected. However, when the target location resumes, and you try to start a full or incremental backup again, the backup fails. Additionally, the following event is logged in the Application log:

Event Type: Error
Event Source: ESE
Event Category: Logging/Recovery
Event ID: 459
Description: Information Store (xxxx) <storage group name>: The file <log path of the storage group>\Exx00000.log is missing and could not be backed- up.

CAUSE

When the backup fails, the incorrect log generation information is written to the database header. The incorrect generation information is visible if you dump the database header by using the eseutil /mh command.

When this issue occurs, an incorrect Log Gen field (0xffffffff) for one or more stores resembles the following:
Previous Full Backup: 
        Log Gen: 1-4294967295 (0x1-0xffffffff)

Restart requirement

You do not have to restart the computer after you apply this hotfix. However, the following services are restarted automatically when you apply this hotfix:
  • Microsoft Exchange System Attendant
  • The Internet Information Services (IIS) Admin Service and all dependent services

Note After you install the hotfix, you have to restart the Exchange Installable File System (ExIFS) service. Because the ExIFS runs as a hidden service, it is not visible in the Services console within the Administrative Tools program menu. However, you can still issue a net stop or a net start command to start or stop the ExIFS service.
