How to build a recovery disk for a XP machine

Hi,
I was wondering if anyone could suggest how to develop a recovery disk for multiple XP machines. I am looking for a disk that would recover system settings, installed programs etc. as opposed to a user’s file, (e.g. docs, pdf, etc.)
Currently, when rebuilding a PC, I have to reinstall the OS and then the various settings. I’m looking to combine these two into a single disk. (This would also be highly benificial when rebuilding a PC/ laptop for a new user.)

I would be increadably greatful if anyone could help with this. Thanks,
Chuck.
