Better. So you have a "poweroff server" command that takes a number and shuts down the appropriate server? So I'm guessing that the poweroff command is not returning until the server actually shuts down.

If that's the case, then perhaps the easiest way would be to use a batch file like:

@echo off
start poweroff server 1
start poweroff server 2
start poweroff server 3
start poweroff server 4
start poweroff server 5

That way, the command shell can fire off the five poweroff commands in their own separate processes.
