My friend just installed windows 7 on a PC and he want to setup a local area connection. It is a HP Compaq dc7900 desktop PC which uses Intel(R) PRO/1000 Gigabit Ethernet Controller. So I asked him to configure the IP adress but he's unable to do so because of this error. I asked him to look at the device manager and surprisingly it shows Intel 82567lm-3 network adapter. So, that's how I figure out the solution, wrong driver for the wrong adapter is the reason you are getting this error.

Just for you information, it is a normal situation where windows automatically determine which is the best drivers for your network card. So it install the driver during windows installation, but keep in mind that the default drivers not always the best. You need to find the latest drivers or download the original drivers from your manufacturer for the best performance and result. Why? latest drivers is more stable and keep up with the latest technology and the drivers from your manufacture is specifically design and tested for you specific model.
