Event ID 38 — Local Time Synchronization

  • Article

Applies To: Windows Server 2008

The Windows Time service (W32time) synchronizes local time with a time source. The Windows Time service on a domain controller can be configured as either a reliable or an unreliable time source. The Windows Time service running on a client will attempt to synchronize its time source with servers that are indicated as being reliable. The Windows Time service can configure a domain controller within its domain as a reliable time source, and it synchronizes itself periodically with this source.

Event Details

Product: Windows Operating System
ID: 38
Source: Microsoft-Windows-Time-Service
Version: 6.0
Symbolic Name: MSG_TIME_SOURCE_UNREACHABLE
Message: The time provider NtpClient has not received response from server %1.

Resolve

Check local network configuration

The Windows Time service cannot contact a valid time source. Perform the following procedures on the computer that is logging the event to be resolved.

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

To resynchronize the Windows Time service with the time source:

  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. The command output indicates whether the synchronization was successful.

To verify the local network connection:

  1. Verify that the network adapter is installed, enabled, and functioning correctly.
  2. Verify that TCP/IP is installed and configured correctly.

For information about configuring and troubleshooting TCP/IP, see Chapter 16 - Troubleshooting TCP/IP (https://go.microsoft.com/fwlink/?LinkId=109262) and Windows Server 2003 TCP/IP Troubleshooting (https://go.microsoft.com/fwlink/?LinkId=109264).

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:

  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. The 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 administrator-configured time server).

To confirm that the Windows Time service was synchronized successfully with its time source when you ran the W32TM /resync command, verify that Event ID 35 appears in the Event Viewer.
