Just speculating,  I thought what if the Hyper v server motherboard and RAID  that dies and I have a 2 week old VHD  clone of Windows 2008 DC on a USB external drive  with Exchange 2010 Server and copy it to  a Hyper v  new server mount it  and restore the Information Store  from backup., what if I have a recent backup exec 2010 system state backup, what are the steps to restore the system state backup ? If I have another DC with a GC , do I need to restore the system state backup?

Well ... restoring DC from VHD in production environment is generally bad idea and is not supported. It might break your replication between DCs (actually it will if not performed correctly) and this itself is a reason to not to do this.

Jorge has put a description on how to do this:

However this is rather 'lab scenario" than production environment procedure.

If you have system state backup You can build OS image from the scratch and then just restore System state on this OS to restore DS function. However if You have another DC in the network it might be actually quicker to build a new OS and just promote it as DC in place of the previous one.

What if there is only one other DC and I demote that before mounting the Windows 2003 DC with Exchange 2010 VHD 2 week old clone.

If there is only one DC and there is no replication with other DCs bringing an old DC image should work with respect to changes made to this directory in these two weeks being gone. So some workstations etc might have problems with password mismatch, some objects might be missing etc.
