Hi All, I'm new to NTP, glad to meet you here.
I did some experiments to test NTP performance on WINNT. In an
isolated network, two machines are inter connnected with a switcher.
Machine A is configure as a stratum 12 NTP server, using lcl as
reference clock; machine B is sychronized to machine

Thank you, David.
In my situation, no GPS is availiable. So can I expect better
performance when GPS is used as reference clock, or when a stratum-1
NTP server is added to the network?
Local GPS or a local stratum-1 server will make a significant difference.

Run ntpd continuously and see if that solves your problem.
Which opens a huge security problem - you should ONLY run NTPd on
systems which are serving time to other systems. Otherwise a simple CRON

Hello,
We use Nagios to monitor our system - you can use one of the prepared
checks (check_ntp_time) to monitor the synchronization of your nodes.
You'll need the NRPE-Plugin for Nagios also. No costs involved (except
your time, of course).
