Configure the domain controller to synch with an external time source such as time.windows.com or pool.ntp.org

Then once thats set configure a group policy to make the internal clients snych from the internal server
For the group policy you need to set the following....

Computer config\admin templates\system\windows time service\
             Set the option global configuration settings(Enable it), the default settings are fine
Now go to Computer config\admin templates\system\windows time service\Time providers

Enable windows ntp client (set to enabled)
Configure windows ntp client (change to enabled and NTP server should be set to the internal name of your server you can leave the rest of the setting alone)
Enable Windowd ntp server should be set to enabled as well

From a domain controller go to command prompt then run gpupdate/force

You should be all set

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

You can import this reg file on your PDC to set the time sync settings automatically.

You can run the w32tm /rsync /rediscover on a client which will sync to the PDC right then. The changes will work. I haven't had one time when the reg didn't sync correctly.

On one of your clients you can go into the event viewer and look under the system option - you should see an entry with w32 time as the header and in the body it will show synchronizing from server....

I did all of these things and when I ran the rediscover command on the client I got "The computer did not resync because no time data was available".

I had to make sure I put my internal computer name correctly in the NTP field:  servername.localdomainname.local

That worked. Just thought this might help someone else.
