VSS problems on Windows 2008 SP2

Hi,

I have a VM running Windows 2008 SP2 that I cannot get Veeam to backup.
It seems to be a problem with VSS:

C:\Users\administrator>vssadmin list writers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.

Waiting for responses.
These may be delayed if a shadow copy is being prepared.

And the Event Viewer on the machine shows:

Event ID: 12297
Volume Shadow Copy Service error: The I/O writes cannot be flushed during the shadow copy creation period on volume \\?\Volume{33c81305-5b5c-11de-b184-806e6f6e6963}\. The volume index in the shadow copy set is 0. Error details: Open[0x00000000], Flush[0x80042313], Release[0x00000000], OnRun[0x00000000].

Event ID: 12341
Volume Shadow Copy Warning: VSS spent 61 seconds trying to flush and hold the volume \\?\Volume{4d9d0013-9968-11df-b2d3-005056886dfd}\.  This might cause problems when other volumes in the shadow-copy set timeout waiting for the release-writes phase, and it can cause  the shadow-copy creation to fail.  Trying again when disk activity is lower may solve this problem.

Restarting the server and WMI and FSRM services does not help.
Any ideas how to fix that?
Thanks a lot!
