My DC has this in the event log and it never sync's its time with my external time source.

Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the AD PDC emulator for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source. It is recommended that you either configure a reliable time service in the root domain, or manually configure the AD PDC to synchronize with an external time source. Otherwise, this machine will function as the authoritative time source in the domain hierarchy. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.

You can configure your PDC emulator to use an external time source using the steps in this article: http://support.microsoft.com/kb/816042

You can opt to use the Fix it or do it yourself. I usually go with the latter as I want to specify what NTP servers I want to use.

As for which NTP servers to use, jump on http://www.pool.ntp.org/en/ and pick servers that are close to you geographically.

After you implemented the registry keys, did you restart the Windows Time service?

Try running this command in an elevated Command Prompt window and post the output:
w32tm /query /status

Open in new window

OK try running this command:
w32tm /resync /rediscover /nowait

Open in new window

Then run w32tm /query /status afterwards - pay attention to the Source value.

The Source still says "Free-Running System Clock", which i am assuming is my problem.  The registry has addresses of external time servers so why does this say "Free-Running System Clock"  How do I change this.?

Can you please post the output from this command? w32tm /query /configuration

I have a feeling something has been misconfigured.

Is it possible that your router is blocking NTP?  You need to have port 123 on your router open in both directions for TCP and UDP in order to be able to sync with an outside time source.

We found a Group Policy setting in the Default Domain Policy that someone must of setup that was overriding the settings that we were changing.  Thanks for all the suggestions.
