Event InformationAccording to Microsoft :
Cause
This event is logged when Windows failed to record Resultant Set of Policy (RSoP) information, which describes the scope of Group Policy objects applied to the computer or user.
Resolution
Correct a Group Policy reporting session failure
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.

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.
