Win7 system manually clears the DNS cache to solve website anomalies

DNS, a distributed database, makes it easier for users to access the Internet. In Win7 systems, we often set up DNS to speed up the network. But sometimes we visit some websites and there are exceptions, because DNS does not work or is abnormal. This situation can be solved by manually clearing the DNS cache. The method is as follows: 1. First run “CMD”, press Enter to open the prompt window; 2. Then enter "ldconfig;flushdns" in the command prompt window that opens, and then enter the command, then press Enter. Then you can start to clear the DNS cache information. The simple three-step process will immediately clear the DNS cache.
