My CA server crashed. It was used to deploy certs to messenger clients for live communication. I am no longer using live communication. I removed the server object from AD but my clients and servers envent logs have a lot of the following entries
Automatic certificate enrollment for local system failed to enroll for one Domain Controller certificate (0x800706ba). The RPC server is unavailable.
DCOM was unable to communicate with the computer msgsvr01.mycompany.local using any of the configured protocols
What else do I need to remove form AD when removing a CA?
