When I searched for this error, the recommendation was to run PSCONFIG.EXE with some parameters but this is a Windows 2003 server and does not have this executable on it.Failed to prepare guest for hot backup. Details: VSSControl: -2147020506 Backup job failed. Discovery phase failed. Cannot enumerate volumes that should be added to the snapshot set. Cannot enumerate volumes that contain components specified by the processed writer. Writer name: [SqlServerWriter], class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. instance ID: [{102a9466-ea81-4754-81ca-9b298c5f7c5f}]. Cannot obtain a volume mount point for the volume that contains the specified file.
There are no errors logged in the Application Event logs for this error, so I have no deeper knowledge of the problem.
Running 'vssadmin list writers' show all of the writers are running and there are no errors.
Can anyone help diagnose and fix this?
