Event ID 10021 - DCOM

Posted on 2009-02-16

Hi There,

I'm getting a recurring error on our SBS server, DCOM, event ID 10021,The launch and activation security descriptor for the COM Server application with CLSID {56BE716B-2F76-4DFA-8702-67AE10044F0B} is invalid. It contains Access Control Entries with permissions that are invalid. The requested action was therefore not performed. This security permission can be corrected using the Component Services administrative tool.

Now although it says, "This security permission can be corrected using the Component Services administrative tool" How do I match up 56BE716B-2F76-4DFA-8702-67AE10044F0B with the component that is causing the error?

Thanks for any help,


PS Please see attached for other errors I'm getting at the same time that seem to be related.

    Applications matching the GUIDs are found when looking in HKCR\CLSID registry key. The GUID posted is related to Volume Shadow Copy Service.
