Who knows the coscom routing settings?

Open the TCP/IP protocol properties dialog box in the local connection properties, then manually configure the IP, fill in the IP casually, such as192.168.0.1,enter the subnet mask as 255.255.0, and click OK.

The reason for the prompt is:

SP2 is more concerned with security. Your IP is set to be obtained automatically, which is actually to obtain the IP and related parameters from the DHCP server, but this process may not be completed for some reason. In the era of SP 1, in this case, the operating system set the reserved IP of 169. X.X of the network card, without giving any error prompt. However, after installing SP2, the operating system does not allocate any IP, and according to the principle of "safety first", the network connection is cut off and the error "local connection is limited or no connection" is reported.

Local connections on the brain show that limited or no connections are related to network servers and network cards. Anyway, it is a network problem, which has little to do with computers and does not affect the system. You can leave him alone. If it is really annoying, you can remove the "Notify me when there is no connection" option in the "Local Connection" setting of "Network Connection". Will not affect the internet.

Intranet, just specify an IP. ........

This is not static electricity.

The TCP/IP protocol of your network card is set to automatically obtain the IP address, but there is no DHCP server in your local area network for your machine to obtain the IP address. So your IP address is not obtained, of course, it is restricted or there is no connection.

The solution is to set an IP address for each network card. On xp: Start-Connect-Show all connections-Select a restricted or unconnected network card, properties-Select the TCP/IP protocol and properties in the "Use the following items for this connection" box, use the following IP address and set it as the IP address on the same network segment as your router (if you don't know, set it to192.168./)
