    Repairing a corrupted COM database.


    by mdfreeman ·

    We have a Windows Server 2003 system, we are using NTBackup for our system backups…these backups are failing. The backup report is as follows:

    Backup Status
    Operation: Backup
    Active backup destination: File
    Media name: “Temp Thursday Backup.bkf created 6/11/2010 at 8:36 AM”

    Volume shadow copy creation: Attempt 1.
    Timeout before function completed

    Error returned while creating the volume shadow copy:0xffffffff.

    Error returned while creating the volume shadow copy:ffffffff
    Aborting Backup.


    The operation did not successfully complete.


    Additionally, two events are created in the Application log:
    Event ID: 20
    Source: VSS

    Event ID: 8193
    Source: VSS

    Event ID 20 flat out says that the COM+ database is corrupt, event ID 8193 indicates a problem with the COM+ infrastructure.

    I have the procedure to repair a corrupted COM+ catalog (re-registering several dll’s, deleting the COM3 registry key, renaming clbcatq.dll and reinstalling COM+); my question is…might following this procedure affect programs installed on the server, i.e. Kerio Mailserver, Symantec Corporate, etc?

      Well, it currently doesn’t work… So re-registering a whole mess of .dll’s isn’t really going to hurt… Worst case it still doesn’t work.

      In my experience, repairing the COM+ works half the time. The other half ended up in a rebuild & restore from backups.

      Best of luck!

        Thanks for the voice of experience, this is the first time I’ve had to deal with this. I guess I’ll let my client know that we may have to do a restore. Any suggestions on how I may be able to get a backup to run in case I have to do a restore? Unfortunately, I just took this server over from another individual and there has not been a valid backup in over two weeks.
