I have a domain server that I've set up as an enterprise certificate authority. While setting up another domain controller as a secondary certificate server, I noticed it would automatically pull from the enterprise controller. I worked through a whole host of things and found something odd. With Certutil -ping, I get a response back when i use the IP address of the server, but RPC server unavailable when I use the server name. DNS is working properly. I can ping the server by address and name as well as fqdn. What could be the problem? Certificate services is running properly, no errors in the event log. Nothing in the security log. I just have a RPC server not found when using certutil -ping and when trying to connect with certificate services mmc. Any help? Or where to look? Acts like it can't resolve the name, but the name is getting resolved.

Hi Wigglethorpe, Do you use command like below? certutil -ping -config "CADNSName\CAName" There is DCOM security issue result in Certutil RPC error.
