Consider the following scenario. You are running a Microsoft .NET Framework-based application in the .NET Framework 1.1 Service Pack 1 (SP1). You execute some Windows Management Instrumentation (WMI) operations that require privileges to be enabled. 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.

        scope.Options.EnablePrivileges = True
        scope.Connect()
        Dim objQuery As New System.Management.ObjectQuery("SELECT * FROM Win32_OperatingSystem")

        Dim objSearcher As New Management.ManagementObjectSearcher(scope, objQuery)

        Dim objCol As Management.ManagementObjectCollection = objSearcher.Get()
        Dim mo As Management.ManagementObject
        For Each mo In objCol

            Dim methodArgs As String() = {"6", "0"} //Forced Reboot

            mo.InvokeMethod("Win32Shutdown", methodArgs)

            Console.WriteLine(mo.ToString())

        Next

    End Sub
