Event ID 9840 When Backing Up Exchange 2007 Information Store

[Guest David Frasca]

We are running Windows Server 2003 SP2, Exchange Server 2007, and Symantec

Backup Exec 11D with the Exchange Agent. When I try to backup the

Information Store Backup Exec fails with a VSS writer error, and the server

reports Event IDs 9840, 9814, 2007, and 2907. When I reboot the server this

fixes it for a while, but the problem keeps resurfacing. Symantec tells me

it is a known issue with 2003 Server and points me to a Microsoft knowledge

base that tells me to dismount and remount my store or to restart the

Information Store service. Neither of these options are viable or practical

in a production environment. I tried to call Microsoft, but they wont

support me on a known issue with their product unless I pay them. Has

anyone seen this and know a fix? Is there anyway to stop this from

happening? Does MS have a patch or are they making a patch that will

address this? I need my Exchange backups to work every time as we all do.
