Hi I'm not very familiar with Hyper-V but after setting up a Hyper-V server and then removing the Hyper-V Role from my Windows 2012 R2 server, it seems like one Network adapter has stopped working. I have a good switchport and cable (verified) and when I plug into this port, I see the network adapter in Control panel showing as cable is unplugged. I then moved to another Windows 2012 server and installed Hyper-V role and setup a virtual server, then removed the server and the role and ended up with the same problem on the second server. it seems like Hyper-V's virtual switch is still holding on to this NIC port. Anyone knows how to free up this port?
Thank you
