Too many people logged in, and the network server crashed, which may be due to the network settings and DNS server. This reason is more common when IP, gateway and DNS server networking methods are manually specified and proxy servers are used to access the Internet. Check the computer's network settings carefully. When IE can't browse the web, you can try to access it with IP address first. If yes, it is a DNS problem, which is caused by an error in obtaining DNS during networking or the DNS server itself. At this point, you can specify the DNS service manually. The address can be a DNS server address provided by the local ISP or a DNS server address that can be used normally in other places.
