通过WCF和IIS c＃上托管的WMI重新启动计算机

Question

I have a WCF Service which is running on IIS. ApplicationPool uses the LocalSystem Identity. The WCF Service has an method for rebooting the system with WMI using the following code:

        ManagementBaseObject mboShutdown = null;
        ManagementClass mcWin32 = null;
        try
        {
            mcWin32 = new ManagementClass("Win32_OperatingSystem");
            mcWin32.Get();

            // You can't shutdown without security privileges
            mcWin32.Scope.Options.EnablePrivileges = true;
            ManagementBaseObject mboShutdownParams = mcWin32.GetMethodParameters("Win32Shutdown");

            // Flag 6 means we want to trigger a force reboot
            mboShutdownParams["Flags"] = "6";
            mboShutdownParams["Reserved"] = "0";

            foreach (ManagementObject manObj in mcWin32.GetInstances())
            {
                mboShutdown = manObj.InvokeMethod("Win32Shutdown", mboShutdownParams, null);
                var result = Convert.ToInt32(mboShutdown["returnValue"]);
                if (result != 0) throw new Win32Exception(result, "Could not restart local machine!");
            }
        }
        catch (Exception ex)
        {
            SkippyLogger.WriteError(ex, "Error in IISAdminService.Restart");
            throw ex;
        }
        finally
        {
            if (mcWin32 != null)
                mcWin32.Dispose();
        }

The method throw an exception with "Privilege not held".

Answer 1

Few things to try...

• this

• Can you run the same method, as LocalSystem outside of IIS - ie host it as a windows service installed of IIS?

• We have a similar system (hosted as a windows service) and it performs the actual reboot using this class.
