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

net stop "Microsoft Exchange Internet Mail Service"
net stop "Microsoft Exchange System Attendant" /y
wait 20
shutdown /Y /T:5 /C /R
