Several of the Windows 2016 servers I look after have been showing a DCOM error which appears as event ID 10016. The error reads “The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {3480A401-BDE9-4407-8C02-798A866AC051} and APPID {30AD8C8E-AE85-42FA-B9E8-7E99E3DFBFC5} to the user xxx SID (S-1-5-21-391 5011649-XXX-2122644135-1731) from address LocalHost (Using LRPC) running in the container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.”
