First determine your PDC Emulator
- Click Start, click Run, type dsa.msc, and then click OK.
- Right-click the selected Domain Object in the top left pane, and then click Operations Masters.
- Click the PDC tab to view the server holding the PDC master role.
- Click the Infrastructure tab to view the server holding the Infrastructure master role.
- 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:
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
