NTP on 8.x seems to much more fragile than it was under 7.x.  It will often show as enabled, but not really be running, especially after network glitches.

From a unix box, run `ntpq -p FILER` and see if NTP is running.  If it isn’t, do options timed.enable off, and then on again.

Subject: 8.0.2p3 NTP issue?

may have hit a bug, but support dosen't show anything yet...

The time is off on an HA pair 3270's running DOT 8.0.2p3 7-mode.  I have other filers that have the same NTP settings and are in synch.  I had to manually set the time on these 3270's before I exceeded 5 minutes for my CIFS clients. 

Has anyone else noticed or dose anyone have any suggestions?

Thanks
