I get this error in the event log on my Issuing CA on startup: Event Type: Error Event Source: DCOM Event Category: None Event ID: 10016 Date: 12/28/2010 Time: 10:58:46 AM User: MyDomain\administrator Computer: MyServer Description: The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID {D99E6E73-FC88-11D0-B498-00A0C90312F3} to the user MyDomain\Administrator SID (S-1-5-21-2722954942-458309614-2947989593-500). This security permission can be modified using the Component Services administrative tool. It doesn't seem to stop any functionality or starting up. I've looked in the registry and found the CLSID is for the CertSrv.Admin component, which I can't find in DCOMCNFG to check the permissions. Any ideas?

Hey Jason, Sorry for the lacking info... OS: WS03 R2 SP2 Yes, the event occurs each time the service is started/restarted No other error events logged correspond to it. The error occurs identically twice on startup. Thanks for any feedback!

Thanks Sumesh, As noted in my original post, I did go into the registry and found the COM component name. That COM component does not exist in DCOMCNFG.
