Strange connection issues

[Mortow]

I'm not sure what is happening. I haven't changed anything on my server or with my clients, hadn't even rebooted, and all of a sudden I am getting 'Error - a timeout occurred' whenever anyone tries to log on. I am using EMULogin on my own private server and haven't had any issues for months. Sometimes when I restart the client, it will let me in but the first time I zone, I get booted to login screen with the timeout error again. I have rebooted everything, server, router, pc etc. I have changed NIC cables (have not tried a new NIC yet). This is happening from outside my network as well. My friends get the same message when they try to log on.

Anyone have any ideas as to what this might be? I have no real error logs to speak of but occasionally I will see the errorcode 10054 pop up in one of the dos windows. I just tried updating the source, thinking maybe a file had corrupted, but that didn't help either.
