Some time ago, when I was dealing with the computer, I found that the computer network symbol was a red exclamation point directly after booting.

Analysis: general connection cable problems, network service shutdown will appear red sigh.

The network card is good, and the connection light is flashing without problem.

As a result, the operating system found that it could not open the network center and entered the service (services.msc). For example, network location awarenss opened its dependency component service and found that it could not be opened (component service in dcom configuration in gpedit.msc), and the operation was invalid.

After judging again, this is a file in the Windows system that is damaged and needs to be repaired, and the restore point is not set, so use sfc / scannow

Repair, and then restart the repair network is available successfully. About sfc Command quoting Baidu Encyclopedia
