Hyper-V "Could not initialize"

Hello Experts!

We have a new SBS 2011 server and have installed the Hyper-V role to run a virtual Server 2003 computer.  Adding the role and setting up the VM works just fine, but when I start the machine I get this error box:


"Virtual Machine Connection"

The application encountered an error while attempting to change the state of "VM-PC".

"VM-PC" could not initialize.


I have contacted the support team for the computer manufacturer and have enabled the proper virtualization settings in the BIOS.  I also tried removing and reinstalling the Hyper-V role at the request of the support team.  That did not help.  But, I found a nice tool from Gibson Research (grc.com) that tests to see if the virtualization settings are right on the PC.  When I removed the Hyper-V role, I used SecurAble (https://www.grc.com/securable.htm) it said that everything was good (see website for tool and screen shots).  After I reinstall the Hyper-V role, it comes up and the last option for Harware Virtualization goes to No even though it was Yes before I installed Hyper-V.

Any ideas?

Thanks!  :)
