SCO Unix and ntpdate

[Brett I. Holcomb]

I've set up several ntp machines on VMS under Multinet and UCX which work 
well - there I can define it so that I can only set my time against the 
master and not affect the master.

Yes, the Win2K is synchronized to another Win2K server that uses one of the 
standard clocks.  This Win2K server is the current master at our site and 
we're synching to it.
