Describe your LAN cabling a bit, and how you connect to

the web:

do you have a simple (non-routing) hub or a router? Do

both PCs

connect to downlink ports on the hub/router/switch? Does

the

uplink port on the hub/router/switch go to a cable/DSL

modem?

Are the cables all standard Cat5 cables, or are some

crossover

cables?

Our Modem plugs into the WAN port of our router, and our
hub is connected through the uplink plug to the LAN port
on the router. Our computers are plugged stright into the
hub. We have no server, but just a peer to peer network
with six computers. We use the CAT5e cables, and no
crossover cables are used in the whole setup.

The cable arrangement sounds OK.

Your router is, most likely, the DHCP server. Since 5 of your 6
PCs get a valid IPA, you should be able to swap stuff to see if
your problem is caused by one of these:
1. Bad port on the hub.
2. Bad Cat5e cable.
3. Bad NIC.
4. Bad DHCP params in the router - for this, use one of the good PCs
to log into the router to see if its DHCP params are sensible. It
is possible that the DHCP server is set to only assign 5 IPAs max.
It is possible that the router is set to filter out the MAC address
of the bad PC.

You should also verify that your hub can really handle 6 LANside ports
*and* a WANside port. Some N+1 port hub/switch/routers are constrained
such that they can handle N+1 LANside ports *or* N LANside ports plus
1 WANside port.
