I am attempting to deploy a Win7 x64 image. The deployment script works fine when i run it with Classical Download option, however, when I change it to use Multicast it fails during the specialize pass of sysprep. Specifically, it fails on the <ComputerName>%COMPUTERNAME%</ComputerName> line of the unattend.xml file.
As far as I am aware, this happens to be the first time that a tokreplw variable/value is called in the unattend.xml file, which leads me to believe that the Token Reply Utility is not accessible.
I know that when using multicast, the image is initially copied to a g: directory. Could this have anything to do with it?
