Event ID 39 — Service Status and Configuration

Updated: November 25, 2009

Applies To: Windows Server 2008 R2

The Windows Time service updates the time server configuration settings or status. Changes to configuration are implemented when the service is restarted and when the W32tm command is used with the /update switch. These configuration or status changes occur when the Windows Time service:

  • Enters a running status.
  • Sets up the log file to record operational information. The debug logging feature of the Windows Time service can be used to help troubleshoot issues.
  • Registers for network configuration change events. Computers use the network to send time samples back and forth.
  • Creates a named event, which is a shared resource that is used for synchronizing time.
  • Saves configuration settings to the registry.

Event Details

Product: Windows Operating System
ID: 39
Source: Microsoft-Windows-Time-Service
Version: 6.0
Message: The time service is unable to register for network configuration change events. This may occur when TCP/IP is not correctly configured. The time service will be unable to synchronize time from network providers, but will still use locally installed hardware providers, if any are available.


Confirm proper TCP/IP configuration

This error indicates a problem with the TCP/IP protocol suite. Verify that the network adapter is installed, enabled, and functioning properly. Ensure that the TCP/IP protocol is installed and configured properly.

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


To verify that the Windows Time service is functioning properly, restart the service, and then check Event Viewer for entries that indicate a successful restart and system time synchronization.

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 functioning properly:

  1. Click Start. In Start Search, type services.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the list of services, right-click Windows Time, and then click Restart.

When the service restarts successfully, the Service Control Manager reports that the Windows Time service has entered the running state (Event ID 7036) in the Event Viewer. The W32Time source in Event Viewer also reports that the Windows Time service is successfully receiving and synchronizing its clock (Event IDs 37 and 35, respectively).
