tool to change the windows xp install code

I have two new dell vostro 220, both have an install code on the box.
one of the pc has a piece of software installed on it by our banking software suppliers that does someking of message service back to there company.
we are trying to make a hot backup site in another town.
since they never gave me the software and told me to just image the box and install it to a like pc that is what I did.
here is the problem now I have two xp boxes claiming to be the same xp install.
how do I change the install code on the pc I imaged to, to what it says on the pc tag.
I have heard there is away to do this.

Whose version of Windows XP is on the box?  Dell's or whose?

Seems odd to wipe a perfectly good, presumably, system in order to make a clone.

You may find that it is an uncooperative OEM version (which is what dbrunton is getting at, I suspect) but you can try this tool

dell oem, to my knowledge that is all dell does

as for wrecking a perfectly good pc so I could clone another one to it.  I didn't see where I had much choice sense the operating system has no importance and the add on software does.  I need it cloned.

so now the only thing is not to get the message when I try to run updates that this computer already exists.  come to think of it both are valid licensed pc's with different ip's maybe microsoft won't notice.
Since I have a lic. for each don't know what it would matter

After cloning a PC, You must go to My Computer Properties, Computer name tab, and change the name. If this is a member of a domain, then it will automatically get a new Machine SID. If this is not part of a domain, then you need to find an old copy of Newsid.exe. I think it has been taken off many download sites, but perhaps you can find it. Run newsid after you have rebooted with the name change, then boot again. You may have to activate windows again, and it may not like the product code of the previous machine, but you should be able to use the code off the sticker on the clone and activate anyway.
