My Logoff.vbs combines this code with that of the reboot and shutdown commands, and allows logoff of remote computers as well.
OS/2 START /PM SHUTDOWN && EXIT  Shutdown Will still stop and ask for confirmation if a non-PM application is active
OS/2 SETBOOT /B  Reboot Unconditional shutdown & reboot from default Boot Manager entry.
(Mailed by Rick Curry)
OS/2 SETBOOT /IBD:C:  Reboot Unconditional shutdown & reboot from C: drive
OS/2 SETBOOT /IBA:nonsense  Shutdown Unconditional shutdown & failing reboot.
Needs Boot Manager installed.
Will reboot, no questions asked, and then stop if nonsense is an invalid Boot Manager menu entry (which, in this case, is exactly what we want).

  1. Hi Doufer,
    The shutdown.exe is a file that is included with Windows. It can be found at the location ‘C:\windows\system32\shutdown.exe'(in XP)

  2. ou have to copy shutdown.exe from a Windows XP machine. Copy it from c:\windows\system32 from the XP machine to c:\windows\system32 on the Windows 2000 PC.
