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.
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:
Ensure the Windows Management Instrumentation (WMI) service is enabled and configured for automatic startup.
Ensure the path, %Systemroot%\System32\Wbem, is included in the PATH system environment variable.
