The problem is: MAC bridge miniport didn't displayed in configure external network menu in Hyper-V manager-> Virtual switch manager.

I am using windows server 2012 RTM with latest updates.

Prerequisites: Hyper-v installed, 2 nics 1GB each drivers installed.

1. Going to network and sharing center -> adapter settigs -> selecting 2 nic's -> create Bridge. MAC Bridge adapter appears.

2. Going to Hyper-V manager -> virtual switch manager -> new virtual network switch -> create -> select external network type .... In dropdown list there are no MAC bridge miniport! Only old adapters, that already used by bridge. Trying to use they return an error.

In windows server 2008 R2 same way i get 2 nic's bridge and virtual machines and physical server working fine.

Any ideas how to solve it?

1. Try to add to bridge virtual network adapter. (bridge->properties->set additional checkbox on virtual adapter). Asked to reboot. After this, bridge disappeared at all, all checkboxes in protocols (adapter->properties) on all afflicted network adapters cleared.
