The XP system won't serve time unless you modify the registry. I guess that 
is perhaps why they are pointing you in that direction. XP doesn't have NTP, 
just a subset of NTP which most people call a broken NTP. You are much 
better off, time wise and security wise, to have the Linux box sync with 
several servers and serve time to the XP.
