Computer can't access network

[Guest]

I have 3 computers hooked to a D-Link switch which also goes to a 5-port
router. These 3 can access each other, and have Internet access. I have 1
computer plugged into the router, which also has Internet access but can not
access the network. It is just 4 computers on a peer-to-peer network.

Are all four computers getting their IP addresses from the router, or
did you set them manually? If the latter, are all 4 IP addresses in the
same subnet (typically, 192.168.0.x)?

If all IP addresses are OK, look for a misconfigured firewall.

If you still can't get it going, in your next post include what version
of XP is on each computer and what error message(s) you get.

Check for "DMZ" or "Isolation Mode" enabled on the port that the problem
computer is plugged into.
