WinXP upgrade to SP2 after the network card can not get IP restricted or no connection

I believe that many WinXP users still retain the genuine system CD, Xiaobian is one of them, using the CD to install WinXP system is the most original Version, when you upgrade to SP2 with automatic update, you will find that the network card can't get IP. If you put the mouse on the local connection, you will be prompted "Restricted or no connection". This problem is also a cliché, and the solution is also relatively simple.
The network card can't get IP, it shows local connection<;restricted or no connection"

Cause: The network card does not obtain resources such as IP address.

Solution: It should be implemented according to the user's network environment.

1. ADSL: Open the local connection property in the Network Neighborhood property, and notify me by canceling the "This connection is restricted or no connection" option or configure the IP address correctly (reserved section: 192.168.1. X) After the problem is solved.

2, unit LAN: should analyze the reason for not obtaining IP, whether the unit network IP is manually specified? Or the router's DHCP function is not open or effective, you should contact the network management debugging.

After WinXP upgrades to SP2, the NIC can't get IP manual solution. Here, there are a lot of automatic repair software. Sometimes the fix can be solved, sometimes it doesn't work. After all, the network The reason is still more complicated. So it is still necessary to learn a manual solution.
