For example, you shut down or restart a local computer by using the System.Management namespace. Or, you may call the ManagementEventWatcher.Start method.
In this scenario, you receive the following error message:
This behavior only occurs on a local computer. This behavior can occur even if the ConnectionOptions.EnablePrivileges property is set to True.
