If you are running the server from the same pc as the client, try this:
Change your world address to localhost or 127.0.0.1 and see if you can log in.....
Also, try changing your zones to localhost or 127.0.0.1 and see if you can log on....
Let me know if either of these work, and we'll go from there...
/edit This may be totally irrelevant, but try taking out the "." (period) in your server name (though I havent logged on in a long time so dont know if others use this character successfully or not... If so ignore the edit)>>>>>>>
