Right-click on the network icon in the lower right corner of your desktop, then click to open the Network and Sharing Center - then click on "Change Adapter Settings" on the left, then right-click on the name of the current network connection, select "Properties", and finally select "Internet Protocol Version 4 (TCP IPv4) Properties" in the network connection properties window, and then you can set DNS.
Method. 2. Refresh the DNS cache.
After setting and modifying the DNS of the machine, the computer may not be able to access the Internet, which is mainly due to the local DNS cache of the computer, and the previous DNS failure will be completely repaired by refreshing the local DNS cache, the specific method is as follows:
1. Use the Windows + R shortcut to open the run dialog box, then type the [cmd] command, and then click "OK" below.
2. In the open cmd command box, enter the run command: [ipconfig flushdns] (after the input is completed, press the enter key to run) to flush the local dns cache.
The above is the solution to the problem that the computer cannot access the Internet due to DNS error, you can follow the steps to access the Internet normally.
