As per the topic, this is an XP SP 2 MVL (Multi Volume Licence) CD. The customer is a school with School Subscription licensing, which enables them to upgrade from Home to Pro. The machine has been cloned off a Scenic E 300, and the build has been resealed with Sysprep. On reboot, Windows briefly tries to start and then reboots.
There is no point in using the supplied disc, as it has XP Home on it. Even if it had Pro, I don't want to have to register a roomful of machines.
As you say, talking to the helpdesk should work, but I thought a quick try on here might work.
