Hi,
URGENT.
We have a major problem at one of our customers at the moment, because or some reason, last night, the Microsoft Information Store service stopped working, with this error:
The Microsoft Exchange Information Store service terminated with service-specific error %%-2147219963.
Situation: Hyper-V Host (2008 R2) with SBS 2011 as VM (Exchange 2010 SP1 UR8).
The Host has Windows Server Backup, which runs eveny day at 23:00 hrs, without any problems for months.
This error occured about 15 minutes after the backup started on the Host. (25:15 hrs).
Restarting the VM doesn't have any effect: the Information Store won't start, and the System Attendant won't start as well.
Since 23:15 last night, I have the above error in the Eventlog every 10 secondes, so the Microsoft Information Store has been trying to start for hundreds of times now. The system log is completely flushed with service stop and start errors.
The Event Application Log is full with:
Unexpected error The operation failed. ID no: 80004005 Microsoft Exchange System Attendant occurred.
We have now clue at the moment. AD is running, everybody is logged on without problems, everything runs fine, time service is good, AD authentication works. This is pretty unbelievable. The error code is nowhere to be found...
Please, as an urgent case, can somebody help us out.
Thanks a lot!
