My Primary Domain Controller keeps disabling the "Local Users and Groups", and when you click on it, you get a message on the right hand side stating the following: "Unable to access the computer (SERVER_NAME). The error was: The RPC server is too busy to complete this operation".
And because of that users cannot access any resources like files or printer on the machine. Only thing that currently works is if you restart the machine, but I would like to know if anyone knows of a permanent solution for this.
Any help would be appreciated.
