80080005 Server execution failed
In one instance we encountered following error on a VEEAM backup environment, where all backup’s failed in the same session. also manually restarting the jobs gave this error:
Unable to subscribe to guest processing components: Retrieving the COM class factory for component with CLSID {D2E3C73F-841A-46B0-A93F-956CCABD3B11} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE))
After investigation it seemed that intl.dll was missing in the …\Veeam\Backup and Replication\Backup\VSS folder.
Replacing it fixed the problem.
