RARP, in particular - ARP requests are for getting MAC addresses given
IP addresses.  I don't know if there are any commands for Windows (or
UNIX, for that matter) that'll send out a RARP request).

If he wants to resolve a MAC address to an IP address because he knows
the MAC address, doesn't know the IP address, but wants to know the IP
address, pinging the box might be a bit difficult....
