The details are missing. Some find it unreasonably but I leave it up to you to supply the details.

But there is a clue in your post. XP today is much too hard for most folk to install proper. And even if you did, later some folk accept a driver from Windows Update and the message you report happens. My answer is "don't accept drivers from Microsoft."

My second answer is "don't update drivers when it works."

Sorry I don't have much else to offer here except you may want to google that "Resource conflict - PCI Network controller on motherboard".
