Checking

    You can check the registry entries if the domain controller is using NTP (should be on PDC) or NT5DS (on non-PDC):

    Find the value of Type under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    You can also check for time advertisement on the PDC by running this command w32tm.exe /resync /rediscover /no_wait, then check for Event ID 139
    To check the source time server: w32tm /query /status

Hmmm ... W32time, the timekeeping service in Windows. I experienced enough trouble with that piece of crap when in NTP mode to avoid using it whenever I can. And it's a pain to configure and troubleshoot.

My recommendation:

Use a Windows port of the classic *ix NTP service, sync a master (or two, three) with an external source (i.e. from pool.ntp.org) and sync the clients and DCs to the master. The NTP service software is free. Easy to install and configure, works like a charm and is stable as a rock. And it is nicer when it comes to one of the rare cases of troubleshooting.

See this article for the "How To".

The NTP service has a low ressource footprint, therefore the NTP functionality could be hooked onto existing machines or VM's like webservers, ftp servers, mailservers or database hosts - even in a DMZ - without visible performance impact.
Did you have any further questions or where you unable to find the values at the registry location specified ?
