First determine your PDC Emulator

  1. Click Start, click Run, type dsa.msc, and then click OK.
  2. Right-click the selected Domain Object in the top left pane, and then click Operations Masters.
  3. Click the PDC tab to view the server holding the PDC master role.
  4. Click the Infrastructure tab to view the server holding the Infrastructure master role.
  5. Click the RID Pool tab to view the server holding the RID master role.

On the PDC Emulator open a command prompt (not powershell)
w32tm /config /manualpeerlist:ca.pool.ntp.org,0x1 /syncfromflags:manual /reliable:yes

To update the values:
w32tm /config /update

To check the configuration status:
w32tm /query /status

And finally to force a client to sync from its source:
w32tm /resync

To reconfigure a machine to get its time from the PDC run the following:
w32tm /config /syncfromflags:domhier /update /reliable:yes

If you need to check your server time against a known source you can use the following command:
w32tm /stripchart /dataonly /samples:5 /computer:pool.ntp.org
