	Assuming you are on the same subnet as the box in question...  Run an
nmap ping sweep on the subnet to find all the machines and then use "arp
-a" to dump your arp table and look for that max address.  Pinging the
broadcast address doesn't always work, depending on the box and
filtering rules.  Pinging the broadcast address might work, though, and
might be worth trying first.  If the broadcast ping doesn't work, then
fall back to nmap.

	Alternatively, if it's a dynamic address, you might check the
dhcpserver.
