To synchronize time in an Active Directory domain, you need to take a few simple steps. First you need to open udp port 123 for the domain controller.
- Launch the command line as administrator.
- Stop the W32Time service:
net stop w32time
- Set the addresses of external time sources:
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
- Now let’s force the controller to respond to clients’ requests for time synchronization:
w32tm /config /reliable:yes
- Start the W32Time time service:
net start w32time
- Check the current configuration of the time service:
w32tm /query /configuration
At this point, time synchronization in the Windows domain can be considered configured
