Thanks. Yes, that's what I tried to do with the slipstream XP SP3 disc I made, but alas, the optical disk problem I had. I was thinking that I might use my external optical drive. However, I don't know which would be faster: starting from scratch and reload 18 computers at the same time (like an assembly line while I wait for all the computers to download the updates which will be slowed down because 18 computers are trying to download off the same line) or slipstream each individual computer one by one (since I only have one disc and one external optical drive).
If it isn't possible, I'm wondering if there is a way to substitute the current drive image into the hidden partition that is currently occupied by the Dell restoration image and use that as the "factory condition". Only problem is that the Norton Ghost that came with the computer doesn't give me the option to replace that image with the current image. The question is would that even be wise to do?
