Event ID 137 — Manual Time Source Acquisition

Applies To: Windows Server 2008 R2

An Active Directory forest has a predetermined time synchronization hierarchy. The Windows Time service (W32time) synchronizes time between computers within the hierarchy, with the most accurate reference clocks at the top. If more than one time source is configured on a computer, Windows Time uses Network Time Protocol (NTP) algorithms to select the best time source from the configured sources, based on the computer’s ability to synchronize with that time source. The Windows Time service acquires a time source peer from the domain heirarchy. By default, computers running the Windows Time service attempt to synchronize time only with a domain controller or a manually configured time source. Currently, the Windows Time service is synchronizing with a manually configured time source peer (as opposed to a time source peer from the domain hierarchy).
