Hello there,
These 10016 events are recorded when Microsoft components try to access DCOM components without the required permissions.
From https://learn.microsoft.com/en-US/troubleshoot/windows-client/application-management/event-10016-logged-when-accessing-dcom, Microsoft says:
"These events can be safely ignored because they do not adversely affect functionality and are by design. This is the recommend action for these events."
However you can try troubleshooting steps from this similar discussion thread https://answers.microsoft.com/en-us/windows/forum/all/error-event-id-10016-distributedcom/130522d2-beac-4495-980a-65e1e3279901
