I would assume Windows, as he said Batch files.
I think you need to make sure that this setting is different for each server, and that nothing else is binding this port:
TCPServerPort=7777
The way I have my servers set up, I have each server set with a set port, then I set TCPServerPort to the UT server port + 4.
i.e. My first UT server runs on port 7880. I set the settings in the UT.ini file to:
Code:
ServerURL=192.168.1.78:7880
TCPServerPort=7784
Server 2 uses this:
UT port = 7885
Code:
ServerURL=192.168.1.78:7885
TCPServerPort=7789
