PsShutdown

PsShutdown is a command-line tool for remote shutdown or Reboot of Computers. PsShutdown is similar to the shutdown utility from the Windows 2000 Resource Kit, but with the ability to do much more. In addition to supporting the same options for shutting down or rebooting the local or a remote computer, PsShutdown can logoff the console user or lock the console (locking requires Windows 2000 or higher). PsShutdown requires no manual installation of client software.

You can use PsShutdown to initiate a shutdown of the local or a remote computer, logoff a user, lock a system, or to abort an imminent shutdown.

Usage: psshutdown [[\computer[,computer[,..] | @file [-u user [-p psswd]]] -s|-r|-h|-d|-k|-a|-l|-o [-f] [-c] [-t nn|h:m] [-n s] [-v nn] [-e [u|p]:xx:yy] [-m "message"]
