 pour arrêter ou redémarrer tu as l'utilitaire "shutdwon.exe" du ressource kit
 
Usage: SHUTDOWN [/?] [\\Computer] [/L] [/A] [/R] [/T:xx] ["Msg"] [/Y] [/C]  
 
/?  Shows this screen.
\\Computer Specifies a remote computer to shutdown.
/L  Specifies a local shutdown.
/A  Abortes a systemshutdown. This is only possible during the  
  timeout period.If this switch is used, all other are ignored.
/R  Specifies that the machine should reboot after shutdown.
/T:xx  Sets the timer for system shutdown in seconds.[20 sec. default]
"Msg"  Specifies an additional message  
/Y  Answer all following questinons with yes  
/C  Forces running applications to close.
  ATTENTION: If you use the /C parameter NT ignores the  
             applications option to save data which may  
             have changed. You will see no File-Save dialog
             box, because NT will force the application to
             close. This will result in a loss of all data.  
             not previously saved !!!
 
pour se déloguer je c plus!

 
Merci infiniment  

ah et merci, sans ironie, aux deux autres posteurs
