How to configure w32time in windows domain

Hi,
noticed recently that a few of our servers have the wrong time including the primary domain controller so wanted to know how to set it up so all the servers and pcs use the primary domain controller to synch time but didnt know how to set it up also so that the primary domain controller uses external clock for synch.  thanks

your default domain settings should have the computers syncing with the pdc

Well, first there is no "primary domain controller" anymore.  But there is role of PDC emulator, and it is that box that should have the external time source configured.

Completed all the commands and no errors so do i have to run any similar commands on the other servers? Also, is there a command to confirm which time provider the pdc emulator is using?

Do I have to go to each server and run a command in order for it to recognize the new time settings?  Im assuming for the workstations this will just happen automatically next time they log into the domain.
