W32Time Event 29

I have been having some time sync issues that are causing all kinds of havoc.  I keep getting an Event 29 in the System Log.  

I just keep getting this error in the logs on all my domain controllers:

"The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible. No attempt to contact a source will be made for 15 minutes. NtpClient has no source of accurate time."

I have manually synced all the servers, My PDC and all the others seem to have the same time running, so I am not really sure why there is this issue.  I have the PDC timed off the CMOS clock so i am not using an external clock.

Any ideas?

All computers in an AD domain refer to the PDC as the ultimate authoritative time server.  First the clients default to the logon DC.  The logon DC defaults to the PDC (sometimes is skipped if logon DC is the PDC FSMO role).  I would suggest that you check the configuration of your time service on your PDC as a place to start troubleshooting.

Here is an article on how to configure properly for both local hardware time and internet service time.  I like to use Tick and Tock (US navy servers), personally.


It also has basic troubleshooting techniques.

I had a registry error that fixed that problem.  One more quick question, should I configure the registry on teh remaining domain controllers to use the PDC as teh NTP server or should I leave them to the default time.windows.com,0x1?

Personally, I would have all my DCs pointing to my PDC emulator for time control.
