I do a ton of work remotely on our 13 servers and always use remote desktop to access them. About 10 days ago I put security patches on all of them and now I can't remote back into one of the servers. It is a domain controller, but not the primary and I can still remote to the primary as well the other domain controller. I still have the option checked for remote access. I had this happen once before and doing a 2nd restart fixed the problem. That hasn't worked. I don't know what else to check - espeically since I can still remote to the other 12 servers.
