I am setting up SBS 2003 so that when I join computers to the SBS, Office XP and other software are installed automatically. I have added the software to the clientapps directory and all users have read/write access. It works great, however my problem is this. I want a complete install without user interface, but I cannot figure out in what file to place the product key so that this screen does not appear during the setup.

Can any one help?
