ntpd is intended to be used in conjunction with a source of time. The undisciplined local clock (127.127.1.x) is not appropriate for this purpose. > 1) The service on the win2003 box takes 2-3 minutes to drop from stratum > 16 to stratum 9.

Restarting ntpd on the linux systems should be sufficient. >Is there a way to configure the linux NTP daemons to sync to the server >even though the server has aged?

Have you thought about adding an IRIG PCI card to the system hosting your "local master ntpd" ?

Keep in mind that your "time island" will drift unless you provide a stable time reference. -- Steve Kostecke <[EMAIL PROTECTED]> NTP Public Services Project - http://ntp.isc.org/ _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
