Hi
I'm trying to backup my virtual DC, running Server 2008 R2. The Computer has all windows updates and Vmware Tools installed. When creating a snapshot (quiesce guest file system is active, but snapshop the VM's memory is not), the creation of the snapshot succeeds, but i get an error and a warning in the event viewer of the VM. The errors are triggered during the snapshot processing.
The error and warning are followed by a series of informational ESENT-Events, freezing all other Shadow copy instances. So the lsass AD is the only one raising an error.
-
Error 489, Source ESENT:
lsass (480) An attempt to open the file "c:\Windows\NTDS\ntds.dit" for read only access failed with system error 32 (0x00000020): "The process cannot access the file because it is being used by another process. ". The open file operation will fail with error -1032 (0xfffffbf8).

Warning 8229, Source VSS:

the error is likely to reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

Because of that, I'm afraid that the backup of my AD might be inconsistent.
Any ideas on how to resolve this?
Thanks in advanced!
