I can't log into my server, others can though

[jimbox114]

This is a new one, for some reason I can't log into my own server now. I have it set up on my new PC, and of course I am trying to log in from my old PC. When I try to log into it I get kicked back to the log in screen. When I log back in I get that message about how I need to patch, etc. I know its a working install of EQ, I logged in to a couple of other servers with no problem.

Odd thing is I am looking at it right now and somebody actually was able to log into my server. They went right in, and have zoned around, etc. I tried again and got the same error though. I have checked around with the settings and everything seems good.

The only two things I can think of is 1> Maybe I do have a firewall on the server PC. It is running Windows 2k, to my knowledge Win2k doesn't not have a firewall program in it? Or maybe 2> My DMZhost is not set right in my router? I changed it to the internal IP of the Server Pc, I also was sure to update my setting at the no-ip website with the server PC. I would think if that was the case though nobody would be able to get in?
