Thanks all for checking on this. I don't want to end up installing to 80 different machines, way too time consuming since the pack takes about 15 minutes per machine from start to finish.
Ideally I can script the silent install on each machine, along with the MBG, and use a GPO to push a script that uses XML to inject a random MAC address into a file, and moves that file to the targetd machines in the proper directory. (c:\programdata\prairie...etc). That's how far I'm willing to go to make sure this is autoamted. In theory it should work.
