Try this: On the one computer (preferably the most powerfull one), go to network connections, right click your network and go options, click Protocol(TCP/IP), and click proporties.
Check the option that says use the following IP address, and type in 192.68.0.1 in the IP field. Do this on the other 2 computers, but change the last digit to 2 and three (ie: on the second computer, the IP will be 192.168.0.2, and the third will be 192.168.0.3)
If that does not work, ill get back to you tomorrow.
