I'm this close....HELP
 

I'm very close to getting my server working. My world loads fine and the zones load fine. I am running a 4 port Linksys router via cable modem network. All the computers on the network can get to the character select screen. When choosing a character, we all get booted back to the server select screen. Here is what boot5zone.bat is saying:
Login Packet 1
Login Packet 2
Client dropped: GetAuthentication=0
Dropping client: process=false

Otherwise, I get no errors whatsoever. Can anyone please help? Thanks in advance :)
