I've got two NICs in my Windows 8 Pro (x64) box each connected to different networks. I would like to release and renew the DHCP lease for just one of the NICs. So far I can't find any way to do it within the ipconfig command.

Is this possible? (perhaps another command or GUI even)

Similar question here, however I'm asking specifically about release/renew functionality.

Yes you can do this. If you look at ipconfig /? you will see the option for ipconfig /renew [adapter] and ipconfig /release [adapter]. So you just need to know the adapter name by typing ipconfig by itself.

Thanks, the /? is good to know. – brack Jun 13 '13 at 14:25
ipconfig /release "adapter name"
ipconfig /renew "adapter name"
