orev Posted September 2, 2007 Share Posted September 2, 2007 When I try to check the shadow storage usage on my system using "vssadmin list shadowstorage", I get an error returned:Error: The shadow copy provider had an unexpected error while trying to process the specified command.and in the event viewer I'm seeing the message:Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {b5946137-7b9f-4925-af80-51abd60b20d5}. Routine details IVssSnapshotProvider::QueryVolumesSupportedForSnapshots(ProviderId,-1,...) [hr = 0x8000ffff].Operation: Query volumes supported by this providerContext: Provider ID: {b5946137-7b9f-4925-af80-51abd60b20d5} Snapshot Context: -1Does anyone have an idea of what this means? Any way to fix it?I'm using Vista Ultimate 64 bit. Link to comment Share on other sites More sharing options...
cluberti Posted September 3, 2007 Share Posted September 3, 2007 Hmm - that's a very uncommon return value for the vssadmin tool, especially on the Microsoft VSS provider GUID (the win32 failure code is E_UNEXPECTED, catasrophic failure). I'd say to uninstall any antivirus/antispyware/backup applications on the machine, including any volume mounting utilities (like daemon tools, for example), and see if the problem continues after a reboot.

orev Posted September 4, 2007 Author Share Posted September 4, 2007 Wow, I'm always amazed at the skill on this site . I removed Daemon Tools, rebooted, and everything worked fine. Then, as a control, I installed daemon tools again. Right after it installed SPTD, vssadmin started giving me trouble again.At least I know who to blame now.Thanks a lot cluberti Link to comment Share on other sites More sharing options...
