Computer NIC cannot get network address

Computer network card can not get network address how to do?

I have a computer network (with other use is the same switch, the other can go up), there is an exclamation point on the local connection, show "local connection restricted or unable to connect", with Ipconfig/all view, the actual address is 00-14-78-20-12-59, IP is 169.254.50.28, subnet mask is 255.255.0.0, network card driver I uninstall after reloading or not, I would like to ask the master door, how to solve?

Unable to get the IP address, the DHCP server is not broken, manually set a, if not to go, it is necessary to consider the problem of physical links

The local connection properties inside the TCP/IP Protocol Properties dialog box open, and then the player moved to configure IP, casually fill in 192.168.0.1 IP, subnet mask input 255.255.255.0, click OK.

The reason for the prompts is:

SP2 more consideration of security issues, your IP is set to automatically obtain, in fact, from the DHCP server to obtain IP and related parameters, but this process may be for some reason, not completed. In the SP1 era, in this case, the operating system to prevent the network To set the 169.x.x.x reserved IP for the network card without any error, if more than one computer does not get the correct IP, then they can communicate with each other through the reservation address. However, after installing SP2, the operating system, based on the principle of "safe" supremacy, does not allocate any IP, disconnects the network, and reports the error "Local connection is restricted or connectionless".

Local connections on the brain show that restricted or connectionless connections are related to network servers and NIC. Anyway belongs to the network aspect problem, with the computer does not have much relationship, does not affect the system, may not have to manage him. If it is annoying, you can in the "network connection" of the "local Connection" settings in the "No Connection notify me" option to remove. Does not affect the Internet;

Intranet words to specify an IP is good.

Not the reason for static electricity.

Your network card TCP/IP protocol, set up to obtain IP address automatically, however, your local area network does not exist can let your machine get IP address of the DHCP server. So your IP address is not secured, of course, restricted or connectionless.

The workaround is to set an IP address for each NIC, on XP: Start-connect to-Show all connections-select the restricted or connectionless network card, properties-Select the TCP/IP protocol in the "This connection uses the following items" box, and use the IP address below, Set to and your router in the same segment of the IP address (if you do not know, set to 192.168.1.2-200) on the OK (do not set to 192.168.1.1, which may be the IP address of your router). This problem is solved.

---------Workaround 1: The method is to open Control Panel-Network connections, locate the current local connection, right-click it, select Properties, double-click Internet Protocol (TCP/IP) on the General tab, and select "Use the following IP address" in the "IP address" Fill in the "192.168.0.1" in the "subnet mask" in the "255.255.255.0", others do not fill out, and then click "OK" to solve the problem. (If the current computer is joined to a workgroup or domain, it should be set according to the situation)

---------Workaround 2 You can remove the "Notify Me without connection" option in the "Local Area Connection" setting of "Network Connections".
