Hi,

I'm use System.Management classes for invoke the Win32Shutdown method (via
InvokeMethod).
I pass the 8+4 argument because I want to power off the computer.

All works fine but the problem is when I use the same code on a windows
service.
If nobody has been logon, the result is a blank screen instead power off the
computer.
(the initial login screen for Windows XP Pro dissapear)

When press Ctrl+Alt+Supr a validation form appear over the blank screen.

My question is if it's possible to power off the computer (programaticaly)
without nobody logon.

Thank you
