Don't know what operating systems those machines run.
On a few Linux systems, ntpd was hacked to run under user id
"ntp", but the install forgot to make directory /var/lib/ntp and/or
the file ntp.drift writeable by user "ntp". If the system
is Unix/Linux, check the user running ntpd by use of the "ps"
utility. Then use "ls -l" to check ownership and privileges
on /var/lib/ntp and /var/lib/ntp/ntp.drift.
