256986 Description of the Microsoft Windows Registry

SYMPTOMS

After you upgrade your Microsoft Windows NT 4.0-based computer to Windows 2000 and then you use W32time.exe to configure the Windows Time service to ignore secondary client broadcasts, your Windows 2000-based computer continues to monitor secondary client broadcasts.

CAUSE

This problem can occur if the timesource value under the following registry key is set to "1":

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


To work around this problem:
  1. Make sure that the W32time.ini file contains the value TIMESOURCE=NO.
  2. Use Registry Editor to view and then delete the timesource value under the following registry key:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

  3. Stop and then start the Windows Time service.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

The timesource setting in the registry is not used by Windows 2000 to configure the Windows Time service. However, if this setting is in the registry, the Windows Time service will monitor secondary client broadcasts.

NOTE: Although W32time.exe may appear to work on Windows 2000-based computers, this service has been replaced by the Windows Time service. Because of this, using W32time.exe to configure the Windows Time service on Windows 2000-based computers is not supported.
