Hyper-V Program Manager
I am feeling lazy today - but thankfully my colleagues have been working hard :-)
Mike Kolitz has done a great series on installing the Hyper-V RC0 bits - with SysPrep, Unattended Installation, and Offline Servicing.
While John Howard has done a two part post on how to configure Windows Server 2008 and Windows Vista for remote Hyper-V administration in a workgroup environment.
To my knowledge there is no SYSPREP provider for Hyper-V and so I wonder if this approach is really supported by PSS? From my personal experience and from validating this approach with PSS many weeks ago myself (prior the post) the results I got back from PSS was that this is not supported.
