I really meant to use nslookup on the XP box to find the XP box's name.  Is
that what you did, or is it the IP of your linux box?  So if your XP
hostname is MY_XP, just use "nslookup MY_XP".

It doesn't mean a lot if the reverse lookup shows an odd name.  Right now, I
get this pointing at my linux laptop from a Windows box:

$ nslookup othello
Name:    othello.<DOMAIN>

$ nslookup
Name:    mar6030971.<DOMAIN>

However, if you can ping the linux hostname, but you can't find it with
nslookup, I think that's an indication that the name is only known via
netbios, not DNS.
