Customer is using Symantec Ghost for creating sysprep images for deployment. Customer has created an image using one of the OEM CD's and has deployed it on 250 GX 620's which worked fine and also on laptops. The installation begins and asks for the product key and once the same is copied from the OEM licence found on the system box the installation progressess smoothly. However customer has now received 3 GX280 for reimaging on which the customer has tried the same image and when the os asks for the product key and the customer provided the key provided along with the system - the program recognises it as an INVALID key.
What can be the issue can you guys help me on this
