Configure Time Service for Domain, PDC

In this post, I’ll briefly run through the process I follow for configuring the time service in a domain, including the PDC Emulator.

There are a couple of considerations and questions you will need to ask yourself
– Is my Forest a single domain or are there multiple domains?
– What is my external NTP Time source?

In my example, I have a Forest with two domains.

In my ‘root’ Forest, identify by the PDC by running the following command on a Domain Cotnroller

dsquery server -hasfsmo pdc

On the PDC, I run the following command.

net stop w32time
w32tm /config /manualpeerlist:”NTP.Domain.Com ntp2.domain.com” /syncfromflags:manual /reliable:yes
net start w32time

Those commands

  • Stops the time service,
  • Configures the NTP server,
  • Configures the PDC as a reliable time source for domain clients
  • Starts the time service again

For the rest of your environment, including the PDC in the child domain, Servers and Workstations, run the following commands

net stop w32time
w32tm /config /syncfromflags:domhier
net start w32time

Those commands

  • Stops the time Service,
  • Configures the Client to use the Domain Hierarchy for Time Syncronisation
  • Starts the time Service again,
