I’ve been trying to back up my main PC with Windows Home Server but Win XP on my PC gives an error in the event log: Volume Shadow Copy Service error: Error creating the Shadow Copy Provider COM class with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a}. I found some instructions to fix this problem and the culprit seemed to be swprv.dll. However, re-registering it with “regsvr32 /i swprv.dll” failed with an odd error code. Opening Component Services from Admin tools revealed that my COM+ catalog was corrupted. These were finally the steps needed:
- Reinstall COM+ by first removing the registry key as instructed here.
- Register swprv.dll as above.
- Re-run backup.
