Synchronizing Time In a Domain

107 Views
Last Modified: 2019-03-19
I have two domain servers (2016) in a virtual environment. I would like to have one server sync to an external time server. I would also like to create a group policy that would force all servers/workstations on the network to sync their time with the primary domain controller. I have read several articles, but through many complicated steps, it doesn't appear to give me   what I perceive to be a simple task.

Can anyone advise on the straight forward steps needed to complete this?

Thanks,

That doesn't seem to be happening like you describe. I have workstations with different times as well as servers. When I query the time service on my workstation, it claims the source as "Free-Running System Clock"
Attached is what my DC currently returns on query.Time Query

Is your DNS set properly?  On the workstations and the servers?  Rather than trying to re-invent the wheel, I would start troubleshooting.  Best place to start is the event logs on both the server and a problematic client.  (DNS is the obvious issue, but if that's not it, go to the event logs!)

So when I googled "Free-running system clock" - I got what I cautioned you about - Disable time sync with the hardware.  Reference:

Once you have fixed the PDC emulator DC, run W32TM /resync /rediscover on your machine.

Thank you for your advice.
I disabled the Hyper-V integration and then re-ran the w32tm command on my DC.

After I ran command "w32tm /config /manualpeerlist:"0.time.windows.com,0x1 1. time.google.com ,0X1" /syncfromflags:manual /reliable:yes /update" on my PDC and then restarted the  win32 service, all domain computers sync'd time with the PDC.

Thanks for the advice!

Thanks for the points, but I think they should be split with Lee.  He had the correct answer first, but focused on VMWare and not Hyper-V.  The original post didn't mention which hypervisor was being used.
