Event Details

Product: Windows Operating System
ID: 1052
Source: Microsoft-Windows-GroupPolicy
Version: 6.1
Symbolic Name: gpEvent_FAILED_ROLE
Message: The processing of Group Policy failed. Windows could not determine the role of this computer. Role information (Workgroup, Member Server, or Domain Controller) is required to process Group Policy.


Determine computer role

Group Policy processing varies depending on the role the computer (workstation, member server, or domain controller). The Group Policy service was unsuccessful in determining the computer role.

Possible resolutions include:

  • Verify the Netlogon service is started and is configured for automatic startup.
  • Restart the computer


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
