Using a work Thinkpad T60 laptop with corporate (locked down) installation
of XP. To facilitate some of the things I need to do, they installed VPC2007
for me.

I downloaded the XP ISO from my technet subscription, as well as the product
ID key. I installed XP within VPC successfully, and now it is ready to
activate. Phone activation is required because I can't install the loopback
adapter on the host due to IT security restrictions. Unfortunately, even
after multiple attempts, the activation window is not providing an
installation ID. So far, everyone I've been able to reach via the activation
hotline tell me that without an installation ID, they can't help me (and
shuffle me to customer support). Customer support isn't familiar with the
VPC at all, and seems to want to try to get someone else to replace my
product ID (which scares me, because I don't know if the new one will
function in the same way as the multi-PC license for the technet
subscription).

Does anyone have any idea why a guest XP OS wouldn't provide an installation
ID within VPC2007?

Thank you,
Keith
