Event ID 1002 — Group Policy Service

Applies To: Windows Server 2008

The Group Policy service is responsible for applying Group Policy to computers and users. By default, the service starts during computer startup and remains operating until computer shutdown. Errors occurring within the core service usually result in a failure of Group Policy processing.

Event Details

Product: Windows Operating System
ID: 1002
Source: Microsoft-Windows-GroupPolicy
Version: 6.0
Symbolic Name: gpEvent_FAILED_ALLOCATION
Message: The processing of Group Policy failed because of a system allocation failure. Please ensure the computer is not running low on resources (memory, available disk space). Group Policy processing will be attempted at the next refresh cycle.


Correct an allocation failure

This error event is usually resolved when the computer returns from a low resource state. Possible resolutions include:

  • Ensure the computer is not low on memory or available disk space.
  • Restart the computer if it has been operating for an extended period.


Group Policy applies during computer startup and user logon. Afterwards, 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
