I do not know if this can help.... for your information. 1) you can check your window firewall setting. If your firewall is on,you can set the exception for port 77. 2) To get all the listenning ports at server, you can try 'netstat /a' command at Server command prompt. -- To test the connection from client, you can also try 'telnet [hostIP] [port]' command at Client command prompt.
