Problem Networking 3 PC's to share broadband connection

[bartdude]

First time writer to forum, so be gentle.
I have 4 PC's all running windows XP Professional that I have linked to a Belkin 4 port cable/dsl gateway router all 4 machines can access to internet, 2 can see the other pc's but cannot access them, message saying you do not have access rights pops up. The other 2 just cannot see any other machine. I have deleted and run the network setup routine in XP but to no avail. All machines have the relavent protocols. Can anyone Help ?

Right-click "My Network Places" and righ-click on the Local Connection and choose properties.

Check the settings and make sure that XP's built in firewall is turned off. ====================================

Thanks for the reply, I have already disabled the built in firewall but it doesn't seem to make any difference

Do all your computers belong to the same workgroup? ====================================

Not only the same workgroup (case sensitive too), but check for user permissions. If the user on PC1 doesn't have any rights on PC2, then logon will be denied.
