Reconfigure a machine to use domain for time sync

Find out how to set a machine to use the domain for its time source.

Q. How can I reconfigure a machines time configuration to sync from the domain hierarchy?

A. Normally the PDC FSMO at the forest root domain will synchronize from an external time server. All other domain controllers and domain members should synchronize from the domain hierarchy. To configure this on every machine (except the forest root PDC FSMO):

  1. Open an elevated command prompt
  2. Run commands:
    w32tm /config /syncfromflags:DOMHIER /update
    w32tm /resync /nowait
    net stop w32time
    net start w32time

If this does not work try again but this time for the resync command add /rediscover.

You can check the time source and state using:

w32tm /query /source
w32tm /monitor
