Remote Reboot

If you need to reboot the remote computer for any changes to take effect you can use the shutdown command line program found on all Windows XP and 2003 Server computers (or available in the Resource Kit for all earlier versions). The command to enter is:

shutdown /r /m computer_name /t 5

/r = restart
/m computer_name is the remote computer
/t = the time before rebooting - any local user will be warned

shutdown /a /m computer_name will abort the shutdown (if you are quick enough)
