I had bought 3 gateway computers 2 years ago and conencted them together on a network. The only way i could see each computer in my workgroup is if i had ipx installed. see i didn't know any better at the time(novice) i didn't think much of it as long as i could see each computer. well now i have to get the boxes working with just tcp/ip because i want to add some server anti virus software that needs to update clients on the network using tcp/ip. a year after our initial 3 computer purchase i added 3 more boxes which can see the workgroup using only TCPIP. I have been comparing the good boxes with the bad and i can't seem to find anything different. I even had a buddy of mine who is very knowledgable about this not find the problem. The boxes are all running xp pro.
