i've encountered this before..make sure both client and server side are in sync..other than that i can't seem to remember what i did to fix it..but i got it to work eventually..

no login = port issue or ip issue. Put your global in connectserverlist, use 127.0.0.1 instead of all other ips in muserverstartup.ini and put your global ip in mapserverinfo ^^
