sysprep comes from microsoft, you can get it from their website or off a full install cd, its part of the distrib packages, you run sysprep on your "model" machine prior to ghosting/cloning it strips the drivers, configs etc etc and forces windows to act like it does when it is first installed on a machine, so it will hotplug to the new hardware if needed, plus you can use it to set new hostnames, and generate new SID's in case you are using a ms AD network
