Hyper-V 2008 core server lost connection with NICs

I had hardware problems with one of our servers, therefore the main board (with on board NIC's) was replaced. The Hyper-V core server is still starting without any problems, including the virtual machines but I can't communicate anymore with the outside world. When I request the IP settings with IPCONFIG /ALL on the core installation I notice that the MAC address is still the MAC address of the old adapters.

After the initial installation one NIC was visible, so we could connect an IP address and start the configuration manager on another machine. This all worked fine. In the current situation (with the new main board) I can also see all four NIC's in the configuration script SCONFIG. The problem is however that these are not attached anymore to a physical NIC because the main board has been changed.

We don’t use teaming on the core server level, we do however on the virtual server level.

How can I change the MAC addresses to the new ones? Or do I need to re-install?
