We have seen several calls from people who are getting this error after installing SP1 for DPM2007.
An Unexpected error occurred during a VSS operation. ID 207 Details: No such interface supported (0x80004002) Recommended action: Retry the operation
This can occur when trying to create new Protection Groups, running Consistency Checks, etc.
The following appears in the MSDPMCurr.errlog :
GetDifferentialSoftwareSnapshotMgmt3Interface () failed: (0x80004002).
This may occur if the IVssDifferentialSoftwareSnapshotMgmt3 interface is not registered correctly with the Volume Shadow Copy Components.
Re-register vss_ps.dll on the DPM server:
From a command propmt issue "regsvr32 %windir%\System32\vss_ps.dll"
You may need to restart the “Volume Shadow Copy” service after performing this step.
If this does not resolve the issue, please follow the steps in KB940032
If performing on Windows 2008, ensure this is done from a command prompt with elevated (administrator) credentials.
