Can't connect to my own server

[nofx712712]

OK, I've been searching for a while now, but I can't seem to find anyone who has run into the same problem as I have. Whenever I host my server I am unable to connect to it, when I do my screen goes black for a sec, like it's about to load eq, then just kicks me back to the login screen. I have tried connecting on other computers on the same network, but the same problem happens on those computers too. There are also no errors when I start up world.exe and boot5zones.bat. Please send me a reply as soon as possible, or a link to a different thread that has the answer to my problem.
