Windows Server 2008 Backup

I've done a "All Critical Volume" Backup on a Domain controller
it produces a VHD file which I suppose I can mounted and open it in Virtual
PC

then I insert it and power on the Virtual PC, whole computer hanged up

I can view the content of the VHD by using tools "WinImage"

is it intended to be used like this or just my thought?

btw I am using Windows Server 2008 RC0 Hyper V 64bit

and I ran "wbadmin start backup -allcritical -backuptarget:f:

Andrew,

2008-based DCs...
