How to sync internet time in Server 2008/ 2012

I found this nice blog on the interwebs which explains how to Configure Windows Server 2008/2012 To Sync With Internet Time Servers.

Basically just execute the following commands on the command line as an administrator

net stop w32time

w32tm /config /syncfromflags:manual /manualpeerlist:"time-a.nist.gov, time-b.nist.gov, time-c.nist.gov, time-d.nist.gov"

w32tm /config /reliable:yes

net start w32time


That will configure the time service to sync with the list of servers (time-*.nist.gov in the above example) and it also tells the server that it is a reliable time source that client machines on your domain can sync with (i.e., w32tm /config /reliable:yes).

If you need to view the NTP configuration, type the following command from a prompt:

w32tm /query /configuration
