Windows 2008 R2 Time Server

Greetings:

I have set up the domain controller with the PDC role to use an external time source.  My windows client still says it is using the time.windows.com.

How do I get the PDC settings onto my clients?  I've restarted the server and also ran a
w32tm /config /update but it is still not polling the information.  I also advertised the PDC as a reliable time source by using both the w32 command and editing the registry.  The service on the server has been restarted as well.  The registry value for the domain controller is correct, the problem is the clients aren't using it as a source.

Windows 7 clients

Run w32tm /resync /rediscover.

If the workstation is connected to the domain then the workstation will get time from the PDC

I ran that command.  I checked the registry and the client says that it is still getting it from time.windows.com even though the server is polling it from somewhere else.  Is that the expected result or should it update it with the name of the pdc server?

Here is the registry on the windows client.  It still points to the default time location.  Not the server name or where the pdc is pulling the time from...

The registry will not change. If the client is pat of the domain then it will update from the DC.

Ok.  Is there a w32tm or some other command I can run from the client so it shows that it is indeed getting it's time from the PDC?

To Resynchronize the Client Time with a Time Server
To open a Command Prompt window, click Start, click Run, type cmd, and then click OK.

At the command prompt, type w32tm /resync /rediscover and then press ENTER.

Note   When you run the preceding command, it redetects the network configuration and rediscovers network resources, causing resynchronization. This rediscovery procedure only works on computers that are joined to a domain. You can then view the event log for more information about why the time service does not synchronize.

Try this w32tm /query /source

Well that at least shed some light on my problem.  when I run netdom query fsmo to get all of the rules I have a computer, lets say dc1 that says it has all the rules.  however when I run the w32tm query source it says that another domain controller is the time server.  however it is not the pdc emulator.

You should be the time server. Run w32tm /resync /rediscover on server and workstation

That seemed to have done it.  However I went to another machine and also had to resync.

Is there a way to force this throughout the environment without typing the command?

No, since this should happen on a reboot
