SCO Unix and ntpdate

[Joel Hammer]

xntpd will start without complaint, but unless you configure it in
/etc/ntp.conf to use the win2k box, it will happily synchronize against
itself without complaint. 

ntp is really scary. Everyone in the world of ntp can be a client and a
server. Like the blind leading the blind. Is the win2k server really
synchronized to a standard clock?
