Thanks nice guide, im getting an error when PE boots on my reference machine "imagex is not a recogised internal or external command" I'm thinking it has not made it onto my disk but I got no errors before this so some words of wisdom would be great, any ideas where i have gone wrong? P.S. Longhorn indeed has multicast ability but unless you have gigabit your not goging to make full use of it I think and its still called wds .
