i do this between several machines here in my department... on the TCP Listen.vi i only wire the port (i use 30000) and a timeout (50ms) and leave the net address unwired. if you have more than 1 NIC you will probably have to wire something to it. then on the other pc with the TCP Open Connection i wire the address of the "server machine" (listener), the port (30000) and the timeout (5000 in this case)...
if you need an example i can wire something up for you good luck Dan
