2 client pcs don't see each other

[Darkdog]

I run a small network of three pcs and a server (windows small business server 2003). I recently set it up. I am no It specialist but I have a problem i can't seem to fix. The 3 client pc are set up the same in every way (all running xp pro). The sever can see and ping all, the one pc can seen and ping all but two can see all when the log on but not ping or connect to each other. Any help here?

Are you running a firewall?? Also are you running DHCP?? Are they all getting IPs??
Try ipconfig /release on the ones having the problems ... after that do a ipconfig /renew and see if they get IP's Do this from the command prompt
Make sure you have adminstrator rights.
