+The PDC Emulator FSMO role is critical because it is the time source for the rest of the devices on the domain.
 In the event that your PDC goes down, you will likely transfer or seize the role onto another Domain Controller.
 The problem with this is the new DC was most likely never configured for an external time source. The solution is to create a Group Policy object that sets the external NTP settings, and create a WMI filter that applies this GPO to only the PDCs within the domain.
