One computer cannot see behind a wifi bridge

Dear people,

I have a network with a 2003 small business server together with a
W2000 workstation on a switch and then a point to point wifi network
bridge, on the other side of the bridge a W2000 workstation and
sometimes a W2000 laptop together on an Router with ADSL.
The server and the router are both DNS servers and are both mention in
the TCP/IP configuration on all the computers.

The problem is that only the Laptop can not see the other side of the
Wifi bridge.
The wifi bridge have a IP number and I can only ping to the side were
the laptop is, when I am on the other side it is the same.

And with out the NetBEUI protocol it (laptop) can not see any computer
at all.

This problem is only with the W2000 Laptop.

I have reinstalled the TCP/IP, I have reinstalled (with the latest
driver) the network card.
But nothing seems to work.
There must by something wrong with the TCP/IP protocol.
Can any one help?

You may want to switch over to NWlink IPX/SPX NetBios compatible on all
machines. I found that Netbeui, WEP,and wireless never played well
together as the wireless NT O/S Win 2K or XP Pro could never share
resources with the other NT O/S machines on the network. NWlink is on all
the machines behind the router. You should uninstall Netbeui first, if
you switch to NWlink.

If going to Netbios, make sure you protect the Windows Networking ports,
which can be done with IPsec that on Win2k, XP and Win2K3.

Dear Duane,

It went worse, The laptop can't even see the other computers on the
same side of the bridge any more.

All machines have to be using NWlink, if you have not done so. If you're
using Ipsec, it should not be giving you problems as far as blocking the
Windows Networking ports.

If the machine cannot see the machines on the same side of the bridge, then
there is a misconfiguration happening.
