ID: Q243993

The information in this article applies to:
  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Professional
  • Microsoft Windows 2000 Datacenter Server
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

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: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).


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 this to be a problem in the Microsoft products 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NOTE: Although W32time.exe may appear to work on Windows 2000-based computers, this service has been replaced by the Windows Time service.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.
