I was running into this problem sometimes when doing a P2V conversion in Hyper-V. The conversion would get to exactly 40% and fail. Every time. Well, after a little searching around, it turned out to be a common problem with the VSS writer on the source machine that is getting converted. Thankfully, the fix is simple and doesn't even require a reboot.
Error (13243)
The snapshot creation failed because the VSS writer {4dc3bdd4-ab48-4d07-adb0-3bee2926fd7f} on source machine MACHINENAME did not respond within the expeted time interval.
(Internal error code: 0x809933BB)
Recommended Action:
Ensure that VSS writer is functioning properly and then try the operation again. 4dc3bdd4-ab48-4d07-adb0-3bee2926fd7f is the Shadow Copy Optimization Writer
You may also see an event ID 8193 in the Application Event Log on the source machine.
The Fix:
- Open regedit and go to HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList
- Under the ProfileList key, delete any subkey that has ".bak" on the end.
Done! You can now complete your P2V conversion.
