VSS not working on server running Exchange 2007 Standard and Server 2003 Standard x64
Posted on 2009-05-07
I'm having a problem where I want to do backups with either VMWare Converter (Remotely) or NTbackup (Locally). VSS is not working.
I get the following error in NTBackup: Error returned while creating the volume shadow copy: 0xffffffff
I get this error in VMWare Converter: [snapshotVolumeFactory,119] Shapshot creation failed. driver=vss
I've tried re-registering all the dll's again, all successful except msxml.dll and msxml4.dll which is normal according to the blogs, and reboot, but it doesn't work. When I run "vssadmin list writers", nothing is returned.
I can start all the services successfully eg. VSS and SWPRV.
These are the commands I ran to register the dll's as per microsoft and lots of other blogs:
cd to windows\system32
net stop vss
net stop swprv
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
This happened after I installed update roll up 6 on the server. Could this have caused the problem?
What can I do to fix it?
Regards and Thanks
