Vista connects to the network in the LAN or other ways, showing that the network connection is normal but can not be solved online

Problem Description

When Vista's machine is connected to the network in a local or other way, the graphs in the network and the share show that there is no problem with the network connection. But still can't get online. The diagnostics display an error message similar to the inability to connect to the DNS server.

Solution

Since the machine has already stored the address of another DNS server in the cache, the machine cannot be connected to the Internet. The solution is as follows: Start --> Run --> cmd --> Use ipconfig on the command line to see if the ip address is successfully obtained. If there are no problems, type nslookup /flushdns on the command line to run.
