Today, I found that the web page suddenly couldn't be opened , But the laptop network connection is normal , Finally, it was found that it was dependent TCP/IP There's something wrong with the agreement , The solution is as follows ：

1、 Start —— function ——regedit.exe, Open registry editor , Delete the following two files ： HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock and HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
2、 find C:\Windows\inf\nettcpip.inf file The document is tcp/ip Agreement documents
3、 Control panel -> The Internet and Internet-> Network and Sharing Center -> Change adapter settings -> Right click to connect -> attribute
First choose TCP/IPv6-> install -> agreement -> add to -> Install from disk -> Then browse through the path and find no 2 Find the file path in step nettcpip.inf, OK then select “TCP/IPv6”.
about ipv4 The agreement repeats the same operation , The final choice TCP/IPv4, namely ： TCP/IPv4-> install -> agreement -> add to -> Install from disk -> Then browse through the path and find no 2 File path in step ,nettcpip.inf And then choose “TCP/IPv4”.

Be accomplished , The browser is finally working
