Virtual disk service terminated unexpectedly
Hi,
All our Domain Controllers are running on Win 2K8 R2. In our environment, EMC Networker is being used as the Backup solution. Lately, we are facing issues with virtual disk service in DCs. Whenever the backup starts, VDS service gets terminated unexpectedly which also results in backup failure. We are able to start the service manually but the issue happens whenever backup kicks in. It's strange that this is happening only in Domain Controllers and backup works fine in other servers which are also running on Win 2K8.
Initially we thought it's due to Networker and we engaged EMC, but they verified this is not an issue from Netwoker end and updated that this could be an OS issue. We restarted the servers but it didn't fix the issue.
Backup keeps failing due to this and we are struggling to get a permanent fix. There are no relevant events we can find in the event viewer to point out the issue.
If anybody has come across this issue and got a solution, please help me...
Thanks,
G

These are virtual servers running on VMware vSphere 5.
It's VSS backup configured on these servers. We already checked the status of VSS writers and they are stable.
These servers are holding only AD DS and DNS roles...
Also, we have checked with Windows Server backup and the issue happens here as well...
Do you know whether MS has released any hotfix for this issue?

i doubt that it is a MS issue. my guess is that it will be a combination of vmware tools and the vss writers, anyway do you know that running DC on virtual machines is not best practice? anyway i recomend you to try the backup with vss:*=off

Backup team upgraded EMC Networker module and we re-registered all the VSS related DLLs. The issue got resolved.
are you running VSS or no VSS backups ? it has no use to backup using vss on the DC either way try the oposite backup aproach and let me know. the issue can be the VSS writers so you can check and compare the output of
VSSADMIN LIST WRITERS
with the servers which do not have the issue and the ones that have the issue.
any other roles on the failing servers?
