I had some issues with VSS on some servers when deploying DPM backup recently. The first few we’re related to netbackup agents installed at the same time as DPM. The solution was removing DPM…however there still we’re some errors on a few servers.
Microsoft PSS Provided the following fix:
Reregister the following dlls in the c:windowssystem32 folder
Net stop vss
Net stop swprv
regsvr32.exe “C:Program filesMicrosoft SQL server80COMsqlvdi.dll”
Net Start vss
Net Start swprv
Reboot the machine and try running the list. If that doesn’t work
Install the hot fix 940349 and reboot the machine.
If that doesn’t work
delete the subscriptions key from the following path
=> once the key gets deleted we restart the com+ services from services.msc
