???? From Windows 2000, About Network Features, Microsoft adds a function called "Media Sense), that is, the system can detect if your network device is connected to the network. For example, we have configured the IP of the machine over the network connection, but if the network card is not inserted, the network is problematic, the IP configured is not enabled. You view IPConfig, or ping you set IP, no. But sometimes our development, testing and other work need to be carried out in a stand-alone environment, and IPs that need to be set are also enabled in this case, what should I do? We can disable the "Media Performance" feature by modifying the registry. The practice is as follows:
???? 1) Add DWORD under the registry: hkey_local_machine / system / currentcontrolset / service / tcpip / parameters:
??? ?????? name: disabledhcpmediasense
???????? value: 1
???? 2) Restart the machine, the IP you set is also enabled without the Internet. Do not believe, ping try. (Note, in this case, IPConfig will not be able to see the set IP, but does not affect your use)
?
???? I also found another way to solve the problem, that is, make a loop network to plug in the NIC. Of course, with the above approach generally doesn't use this way, but you don't know if you know:
???? Making such a network cable: The sequence of the network line of the crystal head RJ-45 is as follows: orange white, orange, green white, blue, blue white, green, brown, brown, the other end does not pick up RJ-45, directly Orange and white, orange, green, other 6 wires can be vacated.
???? After making such a "single-headed wire", insert it to the NIC to allow the operating system to be connected to the network, and naturally you are configured, IP is enabled.
