When you create a Virtual Switch on the Hyper-V, you receive a following error:
Even you try to remove and re-add the virtual switch on the Hyper-V in your Windows 10 machine (Build 1511) (10586.494), you still fail to finish.
And then, you will found you NIC cannot get IP address from DHCP server and also cannot access to the network
The solution is remove and uninstall the NIC Driver, then reinstall it
Problem resolved.
Executive Summary:
When you're configuring a new Microsoft Windows server that has multiple network interface cards (NICs), it's important that you disable any NICs that aren't plugged in to the network. If you don't disable an unused NIC, problems can arise on domain controllers (DCs) running Domain Name System (DNS). The DNS server problems can impede the performance of client computers.
