[Help] Windows XP and Sysprep question

[mannyo]

Quick Question.

I have a large number of PC's that I need to wipe and install a clean XP installation, all the PC's are the same hardware.

The PC's are old systems that are being resold to staff members, so what I want is for the new owner to have to enter the XP Key from the sticker on the case,

What I have done is below.

Install XP, Drivers, and XP SP2 and the PC works fine.

Copy and extract deploy.cab from the XP SP2 CD.

Run sysprep using the reseal option (is that the correct one)

I used ghost to replicate onto another PC to test and the setup works fine, asks for computername user accounts, passwords etc. But knowhere does it prompt me to enter the XP license key. I need it to ask for the key, and not use the same one on each pc due to product activation.

What command line options etc do I need to get the above to prompt for the XP Licence key?.

The version of XP Pro is not the Corp version and uses normal XP Pro keys and not a VLK one, each PC has a unique key stuck onto the base unit.

I have never used sysprep, so maybe I am doing something wrong and a step by step guide would be handy. It has to be said that the people buying these old systems may not be IT literate.
