FSMO role - PDC Emulator - time source

Hi All,
im going to move my fsmo roles to a new server (schema/domain/rid/infrastructure/pdc) - one thing i have read in addition to moving the fsmo roles i need to consider the "time source" for the pdc emulator? how is this done? are these links ok: https://support.microsoft.com/en-us/kb/816042

Am i supposed to use internal hardware clock or external time source??



Decide on your timesource first (ntp.pool.org is a well used one which I will use as an example).

Once you have your timesource decided, run the following command on the PDC Emulator, replacing ntp.pool.org with your chosen ntp server:
w32tm /config /update /manualpeerlist:ntp.pool.org /syncfromflags:MANUAL /reliable:YES

You should then be able to run w32tm /resync and see your servers clock become in sync with the NTP server. This will happen periodically automatically. All your clients will in turn sync their time with the PDC Emulator.

im based in the UK - so was going to run below ? what do you think?

w32tm.exe /config /manualpeerlist:"0.uk.pool.ntp.org 1.uk.pool.ntp.org 2.uk.pool.ntp.org 3.uk.pool.ntp.org" /syncfromflags:manual /reliable:YES /update

w32tm.exe /config /update

Restart-Service w32time

Whats your thoughts on above?



Yup, that'll work. You don't need to bother with the second command as you're already running /update in the first command.



Actually, reread it. The command should actually be:
w32tm.exe /config /manualpeerlist:0.uk.pool.ntp.org,1.uk.pool.ntp.org,2.uk.pool.ntp.org,3.uk.pool.ntp.org /syncfromflags:manual /reliable:YES /update



The 2 links that i always reference are below. The first one tells you how to do it, and the second one provides a great illustration of how it all connects together.
