When using this command to reboot a server, the shutdown process will normally allow about 30 seconds to ensure each running service has time to stop. The shutdown can be made faster if all the services are first halted using NET STOP


net stop “Microsoft Exchange Internet Mail Service”

net stop “Microsoft FTP Service”

net stop “Some other Service”

SHUTDOWN /t:25 /r
