I've read various bits on the forums about this topic particularly the following page http://www.msfn.org/board/index.php?showtopic=26240 where methods for unattended ways of installing the firefox browser are described. However what I've found isnt short and to the point for my simple needs and its really confused me, I dont know what applies to me and what doesnt. I hoped someone could look at what I want to accomplish below and describe the quickest, simplest method: If I have 5 or so computers I want to load XP onto (already with SP1+2) perhaps taking out some bits using Nlite (?) which I then want 4 other applications loaded in the quickest, simplest way possible onto the machines so its all setup up. These will be Firefox browser + Thunderbird mail as defaults with a few extesions, a security suite, burning suite, and office 2003! Can someone please advise the simplest best method in steps, or at least where I can find out more or speak to someone who will know. Thanks.
