I want to configure the Time Service using only GP in a Server 2008 R2 domain. I have created a GP as follows:

Computer Config, Policies, Administrative Templates, System, Windows Time Policy:
=Global Configuration Settings -Enabled w/ default settings.

Computer Config, Policies, Administrative Templates, System, Windows Time Policy,Time Providers:
=Configure Windows NTP Client -Enabled w/ default settings.
=Enable Windows NTP Client -Enabled w/ default settings. =Enable Windows NTP Server -Enabled w/ default settings.

The policy is linked, enforced and applied to Domain Controllers OU. The GP modeling results shows the policy is in effect on the DC (Single DC domain) and the DC is recognized as the PDC emulator. I have run gpupdate /force and logged off/on.

The issue is that the DC shows the time source as internal. I understand I can force this at the cmd line using w32tm to set the peer but I would like to understand what is missing in the GP. The default NTP Client GP setting includes time.windows.com,0x9 as the source but it does not appear to be taking effect.
