Domain time synchronisation

Our network has fallen 3 minutes behind.
I've updated the PDC with the command line...
W32tm /config /manualpeerlist:<timeserver> /syncfromflags:manual

Open in new window

and used 4 popular NTP server addresses

the PDC has now updated to the correct time, but the rest of the network is still 3 minutes behind the PDC.

How do I force the entire network to acquire it's time from the PDC? I thought this was the default action on a Windows domain?

It is.  The other Domain Controllers will sync their time from the PDC Emulator.  Clients and member servers will sync their time from the DCs.  It can take a while for that to happen.

I had many problems with time sync until I set a group policy to force time synchronization to the PDC, Check this I used it to solve all the time sync issues

As I have recently updated the PDC, I will wait a few days to see if clients update.
If not, then I'll look at applying the settings via GPO.

The time did correct itself across the network but it's gone out of sync again.
The PDC is 2 minutes ahead of the computers.

Two minutes is well within the allowable skew.  It's unlikely all clients on the network are significantly off from the PDC's time, unless they're forced to get their time from a different time source.

I applied a new GPO with the settings outlined in that article this morning.
PCs are now matching the PDC!
