Thanks for your quick reply Colin.

I physically unplugged my Linux gateway from the cable modem, then plugged my Win2K machine to it using the same cable. Some time after that I rebooted the cable modem, so it should see the MAC address of the Win2K machine and have no memory of the Linux machine.

Incidentally, under "properties" in windows, the MAC address shows as all zeroes. The NIC is an NVIDIA nForce MCP Networking Adapter. It appears to be a chip on the motherboard, not on a card.

I plugged my Win2K machine directly to the cable modem and configured it to connect by DHCP. I could not get an address for it.

BTW, some newer modems only let you connect one MAC address on residential accounts. Reboot the modem and try again with only that machine, it should work.
