To configure Windows Time Service on Windows Server 2016 so that it acts as an NTP server for domain client computers.
1. Type the following commands on PowerShell:
w32tm /config /manualpeerlist:pool.ntp.org /syncfromflags:MANUAL Stop-Service w32time Start-Service w32time
Now the Windows Server 2016 is an NTP client of pool.ntp.org and its time/clock is synced with the NTP pool servers.
2. On the client machines, run the following command on PowerShell to force them to sync their time/clock with the domain controller on the Windows Server 2016.
w32tm /resync
Time synchronization status can be checked by using the following command.
w32tm /query /status
Which should result in output similar to
Leap Indicator: 0(no warning) Stratum: 3 (secondary reference - syncd by (S)NTP) Precision: -6 (15.625ms per tick) Root Delay: 0.0244810s Root Dispersion: 7.7804107s ReferenceId: 0x8B3BC7D7 (source IP: 139.59.199.215) Last Successful Sync Time: 29/09/2017 08:09:19 Source: pool.ntp.org Poll Interval: 6 (64s)
