Are all three machines set to DHCP

Are you using MS internet sharing on your box?

What is you internet connection? (Cable or DSL on Ethernet, Cable or DSL over USB, or Serial modem)

Does your box (the gateway) have dual NICs or are you trying to route across a ?Virtual IP?(what does MS call this?) two IPs bound to one NIC.

BTW, DON'T Try and remove TCP/IP on an XP machine, you will need to re-install the OS if you do.

You can reconfigure your ipconfig from the commmand prompt. Damn I forget the command(s)- but I am not positive this is necessary in your situation. Give the forum a chance and you will get the right response soon enough I hope.

Look into you IP addressing situation like Pauldriver said...
