[VSSDatabaseExpt] VSS_E_UNEXPECTED_PROVIDER_ERROR (MS SQL database backup in VSS mode)

When performing either a scheduled or manual MS SQL Server database backup job in VSS backup mode. The following backup error are received in the backup report:

The backup error persists even after the following actions have been performed:

1. The MS SQL Server version is updated to the latest service pack / rollup

2. The MS SQL Server has been rebooted

3. The VSS writers have been re-registered using the %OBM_Install_home%\bin\RegisterVSS.bat

Checking the status of the VSS writers using the vssadmin list writers command shows the 'SqlServerWriter' is still in a "Failed" state.

Example:

C:\WINDOWS\system32>vssadmin list writers
