This is pertaining to Windows in general (XP and all recent versions)

After replacing an old motherboard with a new one, the NIC is different, has a new MAC address and generally needs a new TCP/IP configuration. However the old NIC is still somewhere there with its designated IP address and the rest.

Question: is it possible to retrieve those settings (most important is the static IP address) for an old network card that is no longer present in the system?

    @JeremyGibbons You seem to have a very naive outlook on the realities of IT. Oh, yes... we all know the way things should be. But you are not always handed that. Commented Jan 12, 2016 at 5:17

    As a non Windows user, my search for finding old network adapter configs lead me to this post, I'm glad to have found the question asked and a good answer posted. Weird that this was downvoted so much. Perhaps more experienced Windows users have more specific search terms, but I find simple questions like these get overlooked a lot by "proficient" users as if to turn up their noses. Besides, I'd rather see a question even as simple as this asked 50 different ways than in one specific way...

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces]

That registry address contains a list of GUIDs for all the interfaces. Inside those are the connection settings and other information. Not sure if the old card would be in the current config but you could always look at a backup or other older copy to see if you can get the address from there.

  • Thank you for your answer; this was #3 on Google and it's useful for retrieving static IP info off of non-booting windows installs. Grab the old static IP and do a wipe.
