Set server to automatically update time

If you have ever been in the situation where a time server or an old server will just not keep in sync, perhaps due to a CMOS battery error, or simply old hardware, then this cmdlet is for you.

Here is how to set a server to automatically update time;

automatically update time

Open up a command prompt and copy/paste the below:

w32tm /config /manualpeerlist:”0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org”,0x8 /syncfromflags:MANUAL
w32tm /config /update
net stop w32time
net start w32time
w32tm /resync /nowait

All that this is now doing is setting the clock to update automatically from a web time server, the servers we are using are the public pool 1, 2 and 3 at ntp.org
We stop and start the time services, and then tell it to resync with the new settings.
