Setup:
DAG with 4 member servers. All running SME 6.0.4, Server 2008 R2, Exchange 2010 SP2. 3 out of the 4 servers backup fine. The forth server fails with this error:
Error in calling VSS API: Error code = 0x8004230f
Error description: VSS_E_UNEXPECTED_PROVIDER_ERROR
Event Logs log VSS Error 12292 and 13.

All writers are present and showing as Stable.
This issue did NOT occur with 6.0.2 prior to update. After reverting back to 6.0.2 the issue remains and the backups fail.
All VSS related services are present (some set to Manual, but all are functioning correctly).
Backups fail when attempting to backup the server as part of the DAG backup as well as when backing up the server individually (single db/passive only/etc do not make a difference).
Any advise on how to address this issue?
