Event ID 133 — Domain Hierarchy Time Source Acquisition

Applies To: Windows Server 2008

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, the Windows Time service 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. Currently, the Windows Time service is synchronizing time with a time source peer from the domain heirarchy.

Event Details

Product: Windows Operating System
ID: 133
Source: Microsoft-Windows-Time-Service
Version: 6.0
Message: NtpClient was unable to set a domain peer to use a time source because of an unexpected error. NtpClient will try again in %2 minutes and double the reattempt interval thereafter. The error was: %1


Diagnose system issues

The Windows Time service encountered an error when it set the domain peer. This issue may indicate a problem with the operating system or hardware.

Review Event Viewer for other error messages that are related to the system, and resolve them as appropriate. If other event messages do not help to resolve the error, note the details in the event message, and then report this internal error to Microsoft Customer Service and Support (CSS). For information about how to contact CSS, see Enterprise Support (http://go.microsoft.com/fwlink/?LinkId=52267).


To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the Windows Time service is synchronizing correctly:

  1. Open a command prompt as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt. At the top of the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

  2. At the command prompt, type W32TM /resync, and then press ENTER.

  3. At the command prompt, type W32TM /query /status, and then press ENTER.

    This command displays the status of the Windows Time service synchronization. The Last Successful Sync Time line of the output displays the date and time that you ran the W32TM /resync command in the previous step. Also, check the computer name that is shown as the Source. This should be the name of a domain controller (or an administrator-configured time server) in the same Active Directory domain as the local computer.

To verify that the Windows Time service synchronized successfully with its time source, confirm that Event IDs 35 and 37 appear in Event Viewer. If there was a recovery from a previous failure to synchronize with the time source, you also see Event ID 138, which indicates that the Windows Time service is synchronized correctly.
