This error message is displayed after running a network troubleshooter on any version of Windows running Windows 7. It indicates that there is a problem with your DNS server that is causing further problems with your Internet connection.
Your computer appears to be configured correctly, but the device or resource (DNS server) is not responding.
The problem is very popular and people are always looking for new methods to try. We have summarised the working methods we could find and put them into a single article to help future people who are struggling with the same problem. Good luck with solving the problem!
What causes this error?
The list of possible causes is not long and can be expected from a DNS problem. The key to solving this problem lies in its cause. We strongly recommend that you read this list:
Faulty or outdated network drivers are one of the main causes and should be updated as soon as possible. This will prevent future errors from occurring as well.
You may be using the wrong DNS and IP addresses. You should either change to the default settings or change the DNS server to that of Google.
Solution 1: Update or reset your network drivers
To be honest, updating and resetting your driver are two opposite actions, but it all depends on which driver brought the error to your computer. If you are running old, unsupported drivers on your computer, it is almost certain that updating will solve the problem.
However, if the problem occurs after you have updated your driver one way or another; a rollback may be sufficient until a new, more secure driver is released. You should also update or reset the network device that you use to connect to the Internet (wireless, Ethernet, etc.). However, if you perform the same procedure, all devices should not be harmed.
First, you must uninstall the driver currently installed on your computer.
Type “Device Manager “In the search box next to the Start Menu button to open the Device Manager window. You can also use the Windows key + R key combination to open the Run dialogue box. Type devmgmt.msc in the box and click OK or the Enter key.
Run Device Manager
Expand the “Network Adapters” section. This will display all the network adapters that the computer currently has installed.
Update the driver:
Right-click on the network adapter you wish to uninstall and select “Uninstall Device”. This will remove the adapter from the list and uninstall the network device.
Click “OK” when prompted to uninstall the device.
Uninstall your network device driver
Remove the adapter you are using from your computer and navigate to your manufacturer’s site to view the list of available drivers for your operating system. Select the latest one, download it and run it from the Downloads folder.
Follow the on-screen instructions to install the driver. If the adapter is external, e.g. a Wi-Fi dongle, make sure it remains disconnected until the wizard prompts you to reconnect it to your computer. Restart the computer and check if the problem is solved.
Rollback the driver:
Right-click the network adapter you want to uninstall and select it from Properties. After opening the Properties window, navigate to the Driver tab and locate the Rollback Driver option.
Try to roll back the driver if it has been recently updated
If the option is dimmed, the device has not been updated recently as there are no backup files that remember the old driver. This also means that the current driver update is probably not the cause of your problem.
If the option to click is available, follow the on-screen instructions to continue with the process. Restart the computer and check if the problem still occurs in the command prompt.
