Group policy for workstation time synchronization to our domain controller

Is there a group policy for Windows 7 workstations that will cause their clocks to synch with our domain controller?

Also, is there a group policy that controls how often they check in for synching the time?

Thanks,

ALL Domain attatched PC's will sync there time to the domain controller that hold the PDC Emulator role.

We have instances were one of our two domain controllers gets the incorrect time somehow, and then many of the workstations get the incorrect time shortly thereafter.  I wonder if group policy is something that can help with this.

Domain controllers: Windows 2008
Workstations: Windows 7 x64

You need to ensure that the DC that has the PDC Emulator role is correctly configured to get its time from a reliable external time source. Then use the guide i posted in the above link to ensure that the other DC is configured to get its time from the PDC

Heres an article that explains ALL the 2008 GPO settings relating to time.

I would take this approach since you said that one of the DC get's weird with time, it means that it's own time is not synced with PDC & this causes all the clients looking at it to mess up.

On your DC which acts weird with time, run the following in Administrative Command Prompt:
Run them exactly as written.


w32tm /config /syncfromflags:DOMHIER /Update

Net stop w32time

Net start w32time

w32tm /resync /rediscover

Post the result after you run the last line.

If you want to set the Time Service as per GP, then Computer > Administrative Templates > System > Windows Time Service
You will find all related settings there.

Hello Ackles,
I ran the following commands you recommended:
w32tm /config /syncfromflags:DOMHIER /Update
Net stop w32time
Net start w32time
w32tm /resync /rediscover

These all completed successfully.  I'll look into the Group Policy settings available as well.  We'll see how things go from here.  Thanks for your help!
