mmm, do i trust you on that 1 - erm no

anyway im usin xp home !!
Like I said I am not sure XP home has this functionality. XP pro does.

Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]

If you still dont trust it visit GOOGLE

Hope that works.
