XP SP3 Sysprep causing invalid product key
My name's Will and I'm the ICT Manager at a school in Birmingham. I've run into a problem that I'm having trouble resolving and I was hoping some of you guys could help out.
I've created a spanking new image for some newlaptops that we've received and I'm about to Ghost it onto the other laptops.
I always install XP Pro with SP2 from scratch using our Volume Licencing CD and Product Key which I've used for the 3 or so years. I've done the same this time around but to keep the image up to date I downloaded and installed SP3 along with the SP3 sysprep tools.
The problem comes during mini-setup when I come to enter the Product Key. It's saying that the Product Key is invalid despite the fact I'm using the same product key that is a) on every XP pro pc in our entire network, and b) I used to install the image from scratch. I can proceed through mini-setup if I leave the product key blank, but then I have a 25 day activation limit. Obviously any attempt to activate Windows using my VLK is thwarted!
Has anyone else come across this error?
Incidently (or not as the case may be), I installed SP3 on our most recent desktops before sysprepping them, but the difference being I (inadvertently) used the SP2 version of sysprep. This worked without a problem.
Is my image knackered?
Any input will be gratefully received and if you need any more info, fire away...
