The network administrators started their brains and summed up a lot of network troubleshooting skills. However, by carefully reviewing these skills, we can see that some of the troubleshooting skills are performed on the Windows interface. Although these tricks are more convenient for users, it can also effectively improve the efficiency of network troubleshootin
