Event ID 1090 — Group Policy Preprocessing (WMI)

Applies To: Windows Server 2008

Group Policy processing depends on the Windows Management Instrumetation (WMI) service. During preprocessing, the Group Policy service evaluates WMI filters to determine if a Group Policy object is within scope of the computer or users. Failures with WMI can prevent Group Policy settings from applying as well as cause inaccurate reporting results.

Event Details

Product: Windows Operating System
ID: 1090
Source: Microsoft-Windows-GroupPolicy
Version: 6.0
Symbolic Name: gpEvent_FAILED_WBEM_SERVICES
Message: Windows failed to record Resultant Set of Policy (RSoP) information, which describes the scope of Group Policy objects applied to the computer or user. This could be caused by Windows Management Instrumentation (WMI) service being disabled or stopped, or other WMI errors. Group Policy settings successfully applied to the computer or user; however, management tools may not report accurately.


Correct a failed WMI dependency

Group Policy relies on Windows Management Instrumentation (WMI) and the Resultant Set of Policy (RSoP) provider to record policy settings as they are applied to the user or computer. The Group Policy Modeling and Reporting features include in the Group Policy Management Console uses this information to report the applied policy settings.

Possible resolutions include:

  1. Ensure the Windows Management Instrumentation (WMI) service is enabled and configured for automatic startup.
  2. Ensure the path, %Systemroot%\System32\Wbem, is included in the PATH system environment variable.
  3. Use the WMIDiag utility to diagnose the problem further (http://go.microsoft.com/fwlink/?LinkId=92714).


Group Policy applies during computer startup and user logon. Afterward, Group Policy applies every 90 to 120 minutes. Events appearing in the event log may not reflect the most current state of Group Policy. Therefore, you should always refresh Group Policy to determine if Group Policy is working correctly.

To refresh Group Policy on a specific computer:

  1. Open the Start menu. Click All Programs and then click Accessories.
  2. Click Command Prompt.
  3. In the command prompt window, type gpupdate and then press ENTER.
  4. When the gpupdate command completes, open the Event Viewer.

Group Policy is working correctly if the last Group Policy event to appear in the System event log has one of the following event IDs:

  • 1500
  • 1501
  • 1502
  • 1503
