Assign MAC Address of Physical Network Adapter to Hyper-V Virtual Network Adapter

Hi,

I'm new to Hyper-V and virtualization.

I have recently setup hyper-v and installed win7 on one of our company's 2012 R2 server (host).

The 2012 R2 server also serves as the licence tool server for our Maya products.  The MAC address of the physical network adapter is used by the license tool to manage the licenses.  

However, after setting up Hyper-V, it seems the host machine now uses the virtual switch/Hyper-V Network Adapter and the MAC address had changed.  This is causing the license tool to malfunction.

My question is: Is there a way to assign the original physical network adapter's MAC address to the hypver-v virtual network adapter (as if the virtual adapter is the physical one?)

Note: The host 2012 R2 server only has 1 physical network adapter installed.

Thank you!
