Ok, problem i hope you can help out with. I have a server that when i try to remote into one of my servers i continue to get this error that says The RPC Server is unavailable. This happens when i try logging on as a net work admin. When i log in remotely as a local admin i get right in. Also if i take down our DC that handles our AD i can remote right in as a network Admin. This server that is giving me this error is my spam filter which controls incoming mail and forwards it to our exchange server. Not sure if these problems are related, but our emails come in chunks with delays as well.
