We have been connecting to our NC and NUTD server remotely with no problems until this last week. Everything on the local network continues to work smoothly. There are no discernible changes on the server, the router, and client computers. I have installed NUTD on 2 different computers that haven't had it before to see if it is the client computers. But they are not able to find the server either.

I have gone through the router settings to see if there was any change in the port forwarding or firewall, but it hasn't changed. The static IP is the same and the ports are the same. And I can connect through the router to other ports. The server itself seems fine and all local computers connect without a hitch.

Any suggestions?
