FSMO role - PDC Emulator - time source
Hi All,
im going to move my fsmo roles to a new server (schema/domain/rid/infrast
http://binarynature.blogspot.co.uk/2012/04/configure-active-directory.html
Am i supposed to use internal hardware clock or external time source??

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.
w32tm.exe /config /manualpeerlist:0.uk.pool.

then i have run below on the DC that previously had the PDC Emulator: - is that ok or not needed?
w32tm.exe /config /syncfromflags:Domhier /reliable:NO /update
w32tm.exe /config /update
w32tm.exe /config /syncfromflags:Domhier /reliable:NO /update
w32tm.exe /config /update
Only needed if you previously had ntp syncing setup on it.
You should be able to tell by running w32tm /query /configuration.

when i run w32tm /query /configuration on my old DC it come back with NTPServer: local and Type: NT5DS
so will i need to do anything on the old DC that had PDC - it was using the internal windows time

If NTP server is set to local then it wasn't syncing with an external time source. Nothing to do there, just setup the new role holder as above.

last thing on this - i know when servers are setup the DC has the internal NTP set to local - should this be external or does it not matter? Reason is my live environment has 1 DC with all fsmo roles and this is still set to internal NTP time source..
Sorry, I'm not entirely sure what you're asking.
It sounds to me like your existing server is currently running with the default settings which essentially just means internal clock based time. As your entire domain will sync time with the PDC emulator it really is a good idea to ensure you have time sync set up on it.
You could either setup a time source on your current server now, then when you move the fmso roles, set it up again on the new server, or you could just wait for the time being and start from scratch with the new server. It really depends on how long it's going to take you to provision the new server.
I wouldn't worry too much about the config of the old PDC emulator once you've setup the time sync on the new one. If it's still setup to sync with pool.org it will end up at the same time as the rest of the domain anyway, if it isn't setup to sync with pool.org then it will get it's time from the new PDC emulator and, again, end up with the same time being set.

Chris - it's currently setup as internal clock based time so might aswl wait until I setup my new DC. But what I was asking is for example i have 1 DC if I was not going to add another DC so fsmo roles are not moved - Should I change the default internal clock to external time as best practice?
Have you looked at either of my links that i posted? They outline exactly what needs to be done to configure external time source on your PDC.

Will yes I have I just asked as best practice

Whats your thoughts on above?
