We migrated a while ago from SBS 2008 to Windows Server 2012 R2. The new Server is also the Certificationauthority. But when I want to renew a certificate, a get the error messsage "Error: RPC Server is not available".
Since the URL shown in the error message points to "oldserver.domain.local" and not to "newserver.domain.local", this makes sense.
How can I change the address to the new server?
