Updated: November 25, 2009

Applies To: Windows Server 2008 R2

If a computer has been designated as a time provider, it can send the time on to any computer requesting time synchronization at any point in this process.

The Windows Time service time synchronization process involves the following steps:

  • Input providers request and receive time samples from configured Network Time Protocol (NTP) time sources.
  • These time samples are then passed to the Windows Time Service Manager, which collects all the samples and passes them to the clock discipline subcomponent.
  • The clock discipline subcomponent applies all NTP algorithms and selects the best time sample.
  • The clock discipline subcomponent adjusts the time of the system clock to the most accurate time by either adjusting the clock rate or directly changing the time.

Event Details

Product: Windows Operating System
ID: 43
Source: Microsoft-Windows-Time-Service
Version: 6.0
Symbolic Name: MSG_TIMEPROV_FAILED_NETTOPOCHANGE

Resolve

Fix network configuration

The error in Event Viewer should provide additional information. There might be an operating system or network configuration error.

To fix the local network connection:

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

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).

If you are not able to resolve the issue by correcting the network configuration, 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).

Verify

To verify that the Windows Time service is functioning correctly, check Event Viewer for entries that indicate that the service started successfully and that the system time is synchronizing.

Perform the following 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 verify that the Windows Time service is functioning correctly:

  1. Click Start. In Start Search, type services.msc, and then press ENTER. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue. The Services snap-in opens.
  2. In the list of services, confirm that the Windows Time service is running.

When the service starts successfully, the Service Control Manager reports that the Windows Time service has entered the running state (Event ID 7036). The W32Time source in Event Viewer reports receipt of time updates and clock synchronization (Event IDs 37 and 35, respectively).

For more information about the Windows Time service, see the Windows Time Service Technical Reference (http://go.microsoft.com/fwlink/?LinkID=25393).
