aargh, XPsp2 file and printer sharing hell

Hi,

I have 3 machines here, all running the same OS with same updates.
Computers A and B are connected to a D-Link DGL-4300 by wire, and
computer C wirelessly. Windows firewall is disabled, and no other
firewall is enabled.

A hosts an web server, ftp server, and is a file repository. The printer
is also connected to it and shared.

B is gaming and multimedia machine

C is a multiuse laptop.

B and C can access shares on A without problem and can print to the
printer, and from A I can access shares on B and C.

The problem is that B and C won't see each other or share anything with
each other. Pings time out.

All machines are in full DHCP mode, but the router is set to attribute
IP addresses according to the MAC address of the NICs, so all machines
get the same IP each time.

Any idea ?

L.

If you can't get pings to work, getting shares working is gonna be that much
harder.

Are you pinging by address or name? Do either work?
Have you actually checked to see if each system actually has the ip address
you're expecting them to have received from the router?

You sure you don't have some old version of some firewall running on the
non-responsive nodes that really isn't uninstalled like you think?
