DCOM Error Locking Machine

Question

My computer occasionally locks up (does not freeze totally, but the mouse moves so slowly and erratically that it is impossible to control). I end up having to hard shut down every time this happens. When I check the event logs, there are a massive number of DCOM errors (multiple per second). They all show the following error:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 

{53362C32-A296-4F2D-A2F8-FD984D08340B}

 and APPID 

{53362C32-A296-4F2D-A2F8-FD984D08340B}

 to the user DOMAIN\USERNAME (S-1-5-21-451499621-1745117657-844659100-1211) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

I have determined that the CLSID refers to RemoteProxyFactory32 Class in Component Services. However, there are TWO of these in Component Services. One of them I can edit security permissions for, the other I cannot. I have edited permissions in HKEY_CLASSES_ROOT\CLSID{53362C64-A296-4F2D-A2F8-FD984D08340B} so that my user is owner and has full permissions.

I need to know how to either remove one of the entries in DCOM Config or otherwise resolve the DCOM error so I can confirm whether this is the issue or not.

Answer 1

OK I had this same problem on a terminal server.   Outlook 2013 AND 2016 were generating the same problems.   Lockup on one user caused the whole thing to need to have to be rebooted.

I found that there are two keys, but they're different in the fact that one's related to 32 bit and the other 64.   Mine was bombing on the 32 bit key.   I deleted both keys.   Not a problem since.

What gives here ?
