Windows7 system prompts that the network is still restricted to access the Internet

  
Q: My computer uses Windows 7 Ultimate. I found that sometimes there is a warning in the lower right corner that "Network Restricted", but the strange thing is that this time I can access the Internet. What is going on?
A: To know why, you must first understand the principle of Windows 7 to determine whether the network is unblocked. When the computer is connected to the network, Windows 7 will send an access request to a server of Microsoft. The result is displayed as the basis of the Network Connection Status Indicator (NCSI). This function starts from Windows Vista. Specifically, it is Dns.msftncsi.com performs a DNS query, and then requests txt this text file, the content of which is only one line: "Microsoft NCSI", if the result of the query is not correct, Windows 7 will think that the network connection is not normal, thus giving “ Network restricted & rdquo; tips. The situation you are experiencing is due to the failure to properly access Microsoft's servers, so the system believes that the network is not smooth, but this does not affect access to other sites.
