jdow, your advice is precisely what I have attempted to do. Success eludes, clues elude. BTW if I have any system flagged 'stratum' in /etc/ntp.conf I find in /var/log/messages that 'stratum' is an unrecognized keyword, the line is ignored. So I set my /etc/ntp.conf as follows: restrict 192.168.1.0 server sys1 peer sys2 peer sys3 Then I restarted ntpd on all systems (service ntpd restart) Then I changed one system's time, and synching never happened.

Give it an artificially high stratum number even when not externally synchronized. I suspect that would work for you. (Of course, for about $350 you can find HP GPS based time references you can use on that reference computer to keep it exactly on time.) {^_^} ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
