Hi Sacha, Your comments put me on the right track, thankyou. I have nearly zero experience of networks, although slightly more now.
I tried pinging with no message from the other machine and realised I needed a network operating between the 2 machines before I could run a Labview client and server successfully.I purchased a RJ45 crossover patch cable (PC to PC) and I used my Win XP machine which had a fairly painless procedure to setup the network. Finally I retried simple server on one machine and client on the other and success. As a Network novice setting up a TCP link between 2 or more machines, I didnt realise I had get a network running then buy a (patch cable or) hub and cables, then check available machines in the current network by pinging. Ideally I would like to move on further and figure how to talk to machines not on the current network layer but I have a feeling that will involve a lot more resolve. Many Thanks, Regards Chris
