OK, so if the two Wireless machines have not gone off to an ad-hoc arrangement on their own, the wireless part of the Router must be working.
That leaves the Win2K machine and its connection to the Router. It just could be the NIC. I had to fit a cheap (£6) Belkin NIC to the mixed LAN I mentioned above as the HP Pavilion's on-board NIC had failed. Very unusual, but it can happen. Device manager showed it as working OK but it lied.
Another thought. Win2K's Winsock settings are notoriously fragile (for me anyway). I have to use
Winsock Fix
regularly.
Have you done an "ipconfig" at the Command Prompt to check that the IP is within the LAN's expected range. And then there's always the Firewall to consider...
But one thing at a time, eh....?
