Any version of Windows starting with Windows 7 will display this error message after running a network troubleshooter, and it indicates that there is a DNS server issue that is causing additional Internet connection issues.
The issue is fairly common, and people are constantly searching for fresh solutions to test. In order to assist future sufferers of the same issue, we have compiled all of the effective solutions we could find into one article. I wish you luck in solving the problem!
What Leads to This Mistake?
There is a short list of potential causes, and they are all things you might anticipate from a DNS issue. The solution to this issue lies in identifying its root causes, so we strongly advise you to look over the following list:
- The most common cause is due to faulty or outdated network drivers, which should be updated as soon as possible. This will also stop errors from happening in the future.
- It’s possible that your DNS and IP addresses are in error. Either using the default settings or changing the DNS server to Google’s should be on your list of options.
Method 1: Update or Roll back Your Network Drivers.
The driver that caused the error on your computer will determine whether you should update the driver or roll it back. An update will almost certainly fix the issue if your computer is using outdated, unsupported drivers.
A rollback, however, might be sufficient until a new, more secure driver is released if the issue first appeared after you updated your driver in some way. The network device (Wireless, Ethernet, etc.) you are using to access the Internet should also be updated or rolled back, but doing so should be safe.
- You must first remove the driver that is currently installed on your computer.
- To open the device manager window, type “Device Manager” into the search box next to the Start menu button. The Windows Key + R key combination can also be used to launch the Run dialogue box. In the box, enter devmgmt.msc and then press OK or Enter.
- Enlarge the section labelled “Network Adapters”. This will list every network adapter currently installed on the computer.
Refresh the driver:
- Click “Uninstall device” from the context menu when you want to remove a network adapter. This will uninstall the networking device and remove the adapter from the list.
- When prompted to uninstall the device, click “OK.”
- Take out the adapter you’re using from your computer and visit the manufacturer’s website to view the list of operating system drivers that are compatible with it. From the Downloads folder, pick the most recent, download it, and execute it.
- To install the driver, adhere to the on-screen directions. Make sure to keep the external adapter, such as a Wi-Fi dongle, disconnected until the wizard asks you to re-connect it to your computer. Try restarting the computer to see if the issue has been resolved.
Reversing the driver
- Click the Properties option when you right-click on the network adapter you want to uninstall. Navigate to the Driver tab and select the Roll Back Driver option once the Properties window has opened.
- If the option is greyed out, the device hasn’t been updated recently because there are no backup files that would have preserved the old driver. This also implies that your issue is probably not being caused by the most recent driver update.
- If you can click on the option, do so and follow the on-screen directions to continue with the process. Check Command Prompt to see if the issue persists after restarting the computer.
Method 2: Change Your DNS and IP Addresses.
If you’ve previously changed some of these settings, you might want to think about going back to the default settings to fix this issue.
On the other hand, if you have never set up these settings, you might want to try using alternative DNS addresses, like the free DNS address provided by Google.
- Press Windows + R to launch the Run dialogue box, which should open instantly. Type “ncpa.cpl” in the search bar and click OK to launch the Internet Connection settings item in Control Panel.
- Control Panel can be used manually to complete the same process. By selecting Category in the window’s top right corner and clicking on Network and Internet at the top, you can change the view. To access it, click the Network and Sharing centre button. Look for and click on the Change adapter settings button in the left menu.
- After opening the Internet Connection window using one of the methods mentioned above, double-click on your active Network Adapter and, if you have administrative rights, select the Properties button below.
- On the list, find the entry for Internet Protocol Version 4 (TCP/IPv4). To select it, click on it, then click the Properties button down below.
- Remain in the General tab, and if the two radio buttons in the Properties window were set to something different, change them to “Obtain an IP address automatically” and “Obtain DNS server address automatically.”
- If they weren’t, choose “Obtain an IP address automatically,” but this time make sure the box next to “Use the following DNS server addresses” is checked and choose the Preferred and Alternate DNS servers, 18.104.22.168 and 22.214.171.124, respectively.
- To make the changes take effect right away, keep the “Validate settings upon exit” checkbox selected and click OK. After using the network troubleshooter, see if the error still occurs!
Method 3: Clear Your DNS Cache and Reset Your IP Settings.
Many people use this approach because it is so straightforward to address the majority of connectivity-related problems. The ironic thing is that it fixes the issue and users have commented that this was the only action necessary. Try it right away!
- Use the search bar next to the Start menu or the Start menu’s keyboard to look up “Command Prompt.” When the first search result appears, right-click it and choose the “Run as administrator” option from the context menu.
- Another method for opening the Run dialogue box is by pressing the Windows Logo Key along with the letter R. To open the admin Command Prompt, type “cmd” in the dialogue box that appears and press Ctrl + Shift + Enter.
- Make sure to hit Enter after each command you type in the window as you type it. Wait for a message saying “Operation completed successfully” or something comparable to know the technique was successful.
- Check to see if the error still occurs after attempting to reconnect to the Internet.
