How to setup NTP on Windows Server 2008 R2 Domain?

Hi,

I have a 2008 R2 Domain and want to setup up NTP time and sync all my clients to the NTP server. What are the configuration changes that need to be done??

You only need to synch your domain controller server to a internet NTP time server. I have done this setting the NTP server to cronos.cenam.mx in Mexico.

You can use the command w32tm

w32tm /config /manualpeerlist:"0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org",0x4 /syncfromflags:MANUAL

Here is a page with some info

Clients for your domain will automatic synch with your domain controller time if they have windows time service enable (for default it is enable).

But if you want you can config and run a script by GPO with the command

net time /set /y

or w32tm /resync

If you are running within a domain please read this article this will explain in detail how time is distributed in an AD environment.

Read you should only do this on your DC that is holding your PDC emulator.

With the DC that host the PDC emulator role should be enought if they belong to the same site.
