Backups started completing with exceptions a few months back on our file server. The Backup Exec job log lists:
- Snapshot Technology: Initialization failure on: "D:". Snapshot technology used: Microsoft Volume Shadow Copy Service. (VSS)
Snapshot technology error (0x80004005): Unspecified error.
So I checked the Windows Event Viewer and found a number of VSS related errors.
Warning: Event ID 8230
Volume Shadow Copy Service error: Failed resolving account Administrator with status 1376. Check connection to domain controller and VssAccessControl registry key.
Error-specific details:
Error: NetLocalGroupGetMemebers(Administrator), 0x80070560, The specified local group does not exist.
Error: Event ID 8193
Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80070005, Access is denied.
Operation:

Error: Event ID 13
Volume Shadow Copy Service information: The COM Server with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and name IVssCoordinatorEx2 cannot be started. [0x80070005, Access is denied.

If I try a "vssadmin list providers" from an elevated command line (logged in as the domain admin) I get an error stating that i don't have the correct permissions to run the command and that I should run it in an elevated command prompt (which I am) and that access is denied. This also triggers a fresh Error 8230 event in the event log.
I have checked and verified that the VSS service can start and is running as a system account.
One thing that stands out to me is the misspelling of "Members" in the error "Error: NetLocalGroupGetMemebers(Administrator), 0x80070560, The specified local group does not exist."
Not sure if that's a cause or coincidence. Any input appreciated. I'm stumped.
