stonny9,
Thank you for visiting the Microsoft Genuine Advantage Forum. The purpose of this forum is the support of Windows Genuine Advantage (WGA) program. Your question is off topic as well as outside my area of knowledge. I would like to provide some information which may help. There are two types of licenses for XP that consumers will encounter, retail (aka full packaged product), and OEM (original equipment manufacturer).
Retail licenses may be moved from one computer to another, as long as the license is activated on one computer at a time and as long as the previous installation of the license is removed from the previously licensed computer.
OEM licenses for XP are tied to the first computer onto which they are installed and the license is not permitted to be moved on any other computer. For the purposes of defining what a computer is, since a computer is really just a collection of parts, Microsoft has established that the motherboard is the base or "defining" component, and the OEM license is permanently tied to the motherboard.
I'm not quite sure if you are attempting to use the same product key on one machine for another machine. If each machine originally came with a windows xp operating system, (OEM)
please use the COA product key for that machine only.
