That's correct - I've excluded it from DHCP, not shut down the port.
When I tried the nbtstat -A command I was only getting the Computer name of
the known device, not the one I'm trying to track down. Probably because the
known device was still in DNS. Now that I've given the known device it's own
static IP and let the DNS entry die, I only get "Host not found" when I type
nbtstat -A ipaddress. I am able to ping it and get "Reply from..." responses.
