Loss of AD auth due to ntp issues

[An-He]

Quite frequently my Truenas 12 box drifts away a few hours and stops serving smb files correctly.

I did use the orignal freebsd pool servers at the beginning but after having this problem I switched to using internal ntp servers instead,
Unfortunately, that did not help so I have to stop the local ntpd service and manually run ntpdate against any of the servers to get it back to current time.

All the ntp servers we have internally are enterprise switches that doesn't miss a beat ever and I assume the official freebsd pool servers are reliable.

Can anyone give a hint to why this happens now and then ?

SOLVED - System is going back in time (wrong date)

Hi guys! Here I am with this new weird issue. I am running FreeNAS 11.3-U3.1 (updating now to U3.2) and my system suddenly goes back in time. I experienced this looking at some files modification dates and I realized the date was off by 7 days and few hours. I had a look at the NTP servers...

Thanks for the pointers.. Did change to HPET timer and so far everything has been working just fine so that was likely the cause of my problem.
