How have you got them setup exactly?

Are they connected through a hub or a switch then to the router?

Are you using DNS on the router? (Domain Name System)

We need more information so we can help.

Go to Start> Run> cmd> ipconfig. Do this to each computer and list what the results are. BTW do you have them on the same workgroup and each with a unquie computer name?

You are most likely having a DNS / DHCP / or IP problem here.
As posted above you should first check your IP address in Command Prompt (CMD).
If its a 169.xxx.xxx.xxx that means that Windows is assigning you an IP address because it cant get one from your ISP / ROUTER.
If its a 192.xxx.xxx.xxx that means that you are getting a valid IP from your Router / Switch / Hub.
If its anything else you may want to try and renew it by typing: IPCONFIG /RENEW
You may get an error with trying to renew it, but these steps will definatley help you determine if its a communication problem or a blocking issue such as security.

"Could be a whole bunch of other things, but its a good idea to start with some low level testing like this first."

NOTE: If you are getting a valid IP address then you may want to try a PING test to see if communication is working...
Post back for further assistance.
