Windows Server 200x - Shutdown Commands

Shutdown is a command line program available in the Windows Server family, XP and Windows 7.

Shutdown /a -- aborts shutdown

Example: Shutdown  /a  /m \\ computername

1. Shutdown - The basics

Shutdown is a built-in executable in XP and the Windows Server family. Your first decision is do you want a simple shutdown?  If so, use Shutdown /s.  Alternatively, should you desire the machine to restart then type Shutdown /r.

After you issue the /s or /r, a dialog box appears with a 30 second count down, remember to issue the Shutdown /a if you are just testing, or have made a mistake.  Watch out for the dialog box disappearing as you issue the Shutdown /a instruction.

2. Shutdown - Select your victim

Now for the 'Remote' switch /m \\victim.  The full command would be:
Shutdown /r /m \\victim.  The slashes look slightly strange, but that's how it works, in this example, 'victim' is the remote machine name.  None of this is case sensitive so sHUTDOWN /R /m \\ViCTim would work.

Note: There is no space between the backslashes and the computername
\\  victim would be a mistake.

For the local machine, try 127.0.0.1 e.g shutdown /s /m \\127.0.0.1.  Useful in batch files.

Examples for Shutdown switch

shutdown /s /m \\victim    - Shuts down a remote machine called 'victim'

shutdown /r /m \\exchange - Reboots a remote machine called 'Exchange'

Note: For once the sequence of switches is important shutdown /m /s \\ machine does not work.

3. Shutdown - Add the extras

 /t for time.  Is 30 seconds too short (or too long) a time?   You can adjust with /t: 60 to display the dialog box one minute. Maximum is 600 seconds.

/f for force.  'Mr Nasty', is coming - ready or not!  Shutdown /r /f as you may have guessed, restarts the machine and closes any programs without warning.

/c for comment.  Would you like to put your stamp on the shutdown?  Let people know who is in charge, who is shutting them down?  /c " Guy is shutting you down"

/d p:4:1 reason.  Personally, I would avoid this switch, the syntax is tricky the numbers obscure and worst of all it does nothing exciting.  That said the idea is sound, it enters a reason for the shutdown in the event log.  If you activate shutdown's help, then you will get a whole list of major and minor reasons that you could employ with this switch.  For me, this switch is an option, an option that I do not take.

Note 1: Shutdown's switches work equally well with a dash, for example, -d, -r or -a 
(instead of /d, /r or /a)

4. Shutdown - Boring Box

This section deals with a different scenario.  Imagine that you wish to disable the annoying shutdown tracker found on Windows Server 2003.

As is so often the case, when you do not like a feature there is hidden way of turning it off.  In order to disable the Shutdown Dialog box, check out your group policy.  Ask yourself, would this be a Computer policy or a User policy?  The answer is Shutdown Event Tracker is a Computer policy.  Armed with this knowledge make sure that a) You select the OU which containers the Windows 2003 server, b) You navigate to the Computer not the user part of group policy.
