The Microsoft Exchange Information Store resource unexpectedly fails over when you install Antigen 9.0 on a node in a server cluster

This article has been archived. It is offered "as is" and will no longer be updated.
You install Microsoft Antigen 9.0 for Exchange or Microsoft Antigen 9.0 for SMTP Gateways on a node in a server cluster. When you do this, the Microsoft Exchange Information Store resource unexpectedly fails over.
This problem occurs if the Scanjobs.adb file contains more than 16 scan jobs. When this occurs, the Scanjobs.adb file is full. The Scanjobs.adb file can become full if either of the following conditions is true:
  • A virtual server fails over to a different cluster node, and all the scan jobs for that virtual server are created in the Scanjobs.adb file.
  • You use and then delete recovery storage groups in Microsoft Exchange Server 2003. In this scenario, additional scan jobs are created in the Scanjobs.adb file.
