Home networking problem with 3 PC's

[dellboy]

Looking for some help here - I've recently added a 3rd PC to my wireless home network, all PC's are running XP Pro (one with SP2). Before adding the 3rd PC I was able to share files perfectly well between the 2 but since adding a 3rd PC it appaears never to give access to one or more of the PC's even when they're all switched on.

I've run the MS home NW wizard numerous times on each PC, tried using different names etc but still I cannot get full visibility - theres always one PC that can't access the network.

Internet access works fine with all 3 (via a Belkin cable wireless router). Also the Windows firewall is off on the PC with SP2 although the Zonealarm firewall has the IP addresses of the other 2 in the trusted zone.

Anyone got any ideas??

they all using the same workgroup?

are they all using simple/advanced file sharing?

is the workstation service running?

also can you connect to the other pc by its ip?
