Syncing Windows Time service to an external source

It is important to have the Windows Time Service on a DC on the network pointing to an external NTP source to keep time in sync.

There is an article here which tells you how:


I’ve condensed it here to a reg file you can create and run.

Copy the following code into a text document, name it time.reg and run it on a DC.

Then restart the time service with the command:

net stop w32time && net start w32time

Give it a few seconds and the clock should correct itself.

If it is a virtual machine make sure that the Hyper Visor isn’t pushing time out to it, as the server will take that as priority. For example on Hyper-V go to the VM Settings, and Integration┬áServices and un-tick Time synchronization.

The registry file

Windows Registry Editor Version 5.00

“NtpServer”=”0.europe.pool.ntp.org,0x1 1.europe.pool.ntp.org”
