Unable to get time to sync on Server 2012 R2 DC
-
I'm reading that if it is off only by a few minutes it slowly changes the clock to run faster until it 'catches up'.
Check again in the AM and report back.
Goodnight all.

That's correct.
-
With the fact that it slowly 'catches up' last night I adjusted the time to be within 2 minutes of current time hoping that it would 'catch up' more quickly. As of this morning it's still at 2 minutes behind, so no joy....
-
When I've had time sync issues in the past to help I've just installed a atomic clock sync tool onto the server.

Check Group Policy setting in the default domain controller OU to make sure NTP/SNTP is not disabled. See this article:

Also, try an IP address instead of name. I use 132.163.4.103 and 129.6.15.29 for my testing, then set to pool.ntp.org when testing's complete. -
@hobbit666 I have tried a couple of those.
It's weird to me as it seems like it's able to sync the time, but no matter if it is 7 minutes late or 2 minutes late the server 'thinks' it's off by 0 ms so it doesn't change.
It's just odd.
-
@ccwtech as long as it is in between 5 minutes from the right time it should be okay.
-
@dbeato But it doesn't. I manually changed it from 7 behind to 2 behind to let it catch up. However I have set the time on this server (to correct time) manually a couple months ago and that is when the company called me and said it's off again.
-
@ccwtech Last thing to check is the actual server hardware clock then

Yeah. Two should be well within tolerance.

Oh. This is a VM? Is the hypervisor and the VM the same?

He said in a earlier post
Physical box (no VM).

Oh sorry, missed that.

I put a new CMOS battery in, made sure the time in BIOS was correct. It's now about 30 seconds behind. Seems like it gradually keeps slowing until manually entered again.

Maybe the clock has gone bad?
-
Is there any test for that? I would imagine the fix is a new motherboard, right?

Well, is the time drifting on the server? Sounds like the clock is bad
Can you offline the server for a while and see how quickly the clock drifts when the OS is not running?
-
@ccwtech I would check again what is the main NTP server on the servers and adjust the Time ZOne on the server.

The time zone is correct and I have tried several different time servers. What I see is that it is contacting the time servers as it should, but no matter what time is on the server it shows a 0 ms offset from the NTP servers.
-
are any of your time services running under a domain accoutn instead of Local Service? Sounds like a service does not have permission to update the time
