Yesterday I've installed Hyper-V 2012 and I've forgotten to plug Intel LAN card. Hyper-V has detected built-in Atheros LAN device. Now how can I install the external LAN card automatically? Should I use pnputil and driver CD?

  • I'm not sure I understand what your problem is. Can you please be more specific ? – Stephane Jun 13 '13 at 9:58
  • Can Hyper-V 2012 recognize & install the newly added device drivers automatically where installation already done? – Nime Cloud Jun 17 '13 at 7:36

Yes, use pnputil. Specifically:

pnputil -i -a drivername.inf

This will bring your NIC on line. Then you'll want to create a virtual switch on top of it.

You also could have installed the drivers off-line with dism.exe, if you wanted to inject the driver into the Hyper-V image before installing it on a machine.

  • Probably Hyper-V installation could detect & recognize Intel Lan card. Next time I'll plug it then install Hyper-V. – Nime Cloud Jun 17 '13 at 7:40
  • Plus the cable should be plugged to be listed, IMHO. – Nime Cloud Apr 3 '14 at 22:15
