I fiddled around with the virtual network settings of my Hyper-V server, because Windows Update failed to run in the VMs. I set the flag that makes the NIC exclusively usable by the VM. Now, the host system tells me it has no active network adapters.
What does that even mean? According to netsh, there are three enabled network connections. I tried to restart the NICs using devcon.exe (the correct x64 version), but that doesn't make any difference – still, devcon reports the NICs are there and they are activated?!
Is there any way I can force the host (using the console) to re-enable the NICs?

Undo your change.
Logically - if the NIC is reserved exclusively for the VM, obviously the host can not use them anymore.
Open the settings for the Hyper-V networks you created. you can turn them on there for the host, too (so that the host and the VM's can use them).
