The error can be cause by installation of the DHCP role on the SQL server, resulting in the Network Service account losing the permissions on the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Diag
The problem is related to the installation of the VSS module DHCP Jet Writer, which is responsible for correct shadow copy creation of the DHCP service. This VSS module changes permissions on the specified registry key during the installation.
To resolve the issue, assign Full Control permissions to the Network Service account for the registry key:
ms, sql, dhcp, vss, nonretryable, denied, deny, mssql
