I have a Domain controller which also acts as our print, 2nd DNS, and DHCP server.
Recently, we've started getting a bunch of errors with the server that I have no idea how or what to start with to correct.
1. Shortly after a reboot we cannot connect to the server via Remote Desktop. We get the error that they system cannot log you on due to the following error: The RPC server is unavailable.
2. The server cannot browse the network. It cannot connect to any of the other servers in the domain but they can connect to it.
3. I've run a dcdiag and I get replication errors in AD. But, I'm unable to access AS users and computers while getting the error message "naming information cannot be located because: The target principle name is incorrect.
Some guidance would be greatly appreciated. This is a production server and it's currently the busiest time of the season (Accountants).
