Event ID 14 — Domain Hierarchy Time Source Acquisition
Applies To: Windows Server 2008
.jpg)
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: | 14 |
| Source: | Microsoft-Windows-Time-Service |
| Version: | 6.0 |
| Symbolic Name: | MSG_NO_DC_LOCATED |
| Message: | The time provider NtpClient was unable to find a domain controller to use as a time source. NtpClient will try again in %1 minutes. |
Resolve
Investigate the problem with the domain time source
The Windows Time service is synchronizing time with a backup time source that is configured manually. This indicates that there is a problem in communicating with the primary time source. Ensure that the domain time source is online and responding to clients. Resynchronize the client with the time source peer. Perform this procedure on the computer that is logging the event to be resolved.
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.
To resynchronize the client with time source peer:
- 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.
- At the command prompt, type w32tm /resync, and then press ENTER. The command output indicates whether the synchronization was successful.

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