Hyper-V in Windows 8.. VM cannot get DHCP IP address

I had Both Virtual Box and Hyper-V on the same machine, I decided trying to shut down Hyper-V all the time was too much trouble so I removed VirtualBox.

Since then no machine can get a local IP address from the router.

I have even setup the virtual connections again:

I have various CentOS installs which I installed with generation 1.

I even tried changing the LAN Adapter to a "Legacy" one, but it still fails.

Any advice as to what is going on with this?

Thanks
