Event ID 1091 — Group Policy Reporting

Applies To: Windows Server 2008

The Group Policy service maintains a reporting system. This allows client-side extensions to report the policy settings they apply to the user or computer. Tools such as the Group Policy Management Console (GPMC) and GPResult display this reporting information to the user. Usually, Group Policy reporting problems do not prevent Group Policy from applying. However, reporting information may be incomplete if reporting errors occur.

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
