Download sysprep for Windows Vista and sysprep the image machine. Pull the hard drive out and then ghost it to the other machines hard drives. When you boot them up it will run through the wizard and auto configure what ever info you configured sysprep for. If you don’t want to deal with the ghost licenses you can put the master drive as a secondary drive, and then drop the new drive as another slave drive and robocopy the disk over, then it should be ready to be booted off of. When it boots it will still run through the wizard.
Make sure that you get the new version of sysprep as Vista needs a different version as Windows XP and Windows 2003 server.
