3 out of 4 computers work with home network, why won't the 4th?

[DieselPUmp]

I have 4 computers networked here at home.
All running Win XP Pro.
3 of them have no problem accessing each other, sharing the files and printer. One cannot use the printer, share anything, or be accessed by any of the other 3.

Does anyone know why this is?
How can I solve this problem?

Thanks

is it added to teh workgroup?
if its a wireless network try changing the security type (may be corrupted on the 4th)
is it allowed in the firewalls?
can you ping the non working comp from a working comp?
can you ping the router from the non working comp?

Did you remember to enable printer and file sharing on the troublesome PC?

It is added to the workgroup, not a wireless network.

I disabled windows firewall, and it is allowed on my software firewall.

I'm not sure how to go about pinging the other computers or the router, how do I go about this?

Thanks

Switch or router?
Can you ping the administrator PC from one that is not on the network?
