Hello everybody!
In today’s video, I’ll show you how to fix a problem with Internet connection, namely,
“DNS server is not responding.”
DNS server issues are among the most widespread errors related to Internet connections.
Once such error appears, there is no Internet connection, the icon in the system tray becomes
like that, and if you open a browser to visit a website, you will see messages like «Server
DNS address could not be found», «error name not resolved» and so on.
This problem is caused by a failure of the DNS server which is in charge of redirecting
the IP address.
In today’s video, we will go into what could trigger such an error and how to fix it.
Why it happens The problem can be caused by your computer:
DNS service not running, wrong network settings and so on.
The router: malfunction or wrong configuration.
Your provider’s equipment can also cause the trouble.
Most modems are configured to receive DNS settings automatically from the provider’s
servers.
Sometimes, provider’s servers (or modems) may work too slowly or incorrectly, which
results in various Internet connection issues.
Solutions: Restart the computer and the router
The first thing to do before you start troubleshooting is to restart the computer and the router.
With the router, this can be done by unplugging it from the power outlet for about 20 seconds,
or by pressing the power button (if your device has it, of course).
When both devices restart, begin the network diagnostics.
You can do it by right-clicking on the network icon in the system tray and selecting the
line Troubleshoot problems.
After diagnostics, the network will either start working again, or you will see the error
“The DNS server isn’t responding.”
Connect another device to the network The next step to take is to check if the Internet
connection works correctly with another device.
If your computer receives the connection through the router, check if other recipients working
with this router have any network issues, or DNS server problems.
For example, connect your phone to this network to see if connection can be established and
if there are any errors involving DNS server.
If the problem is caused by something in your computer, other devices will work properly
with the Internet.
In case your computer is connected through the router, try establishing an Internet connection
directly, without the router.
Unplug the network cable from the router, and stick it into the network port of your
computer instead.
Also, it would be useful to remember when exactly the DNS error appeared and what you
were doing before Internet connection problems began.
You may have changed certain settings or installed some software.
Start DNS client service Before you configure the settings, check if
the DNS Client service is running.
Open the Services window.
Press the key shortcut Win+R and run the command services.msc, or look for services in the
search field.
In the window that opens, find DNS Client service, right-click on it and select “Properties.”
The startup type should be “Automatic.”
If the “Start” button is active, click on it.
Then click “Apply" and "Ok".
If the service was stopped and you started it, the Internet connection should be restored
as soon as you restart the computer.
If your situation is different, try another solution.
Configure DNS server The next step is checking DNS server configuration
in your network and Internet settings.
If there are some addresses in the corresponding fields, you can configure the settings to
receive addresses automatically, or use DNS addresses by Google.
This method often helps us to get rid of the error “DNS server is not responding.”
Open Settings / Network & Internet / Network and Sharing Center / Change adapter settings.
Right-click on your Internet connection icon and select “Properties.”
If your computer receives Internet by cable, it should be Ethernet, and if you’re on
Wi-Fi – it’s a wireless network.
In the window that opens, select IP Version 4 and click Properties.
If you have a certain DNS server assigned, check the option for “Obtain DNS server
address automatically” and click OK.
Restart the computer and check your Internet connection.
If you have configured this connection to obtain the address automatically but there
is no Internet, using Google addresses may help.
Check the option for “Use the following DNS server addresses” and type the preferred
DNS server address 8,8,8,8.
And the alternate DNS server address – 8.8.4.4.
Click OK and restart the computer.
In most of the cases, this should fix your problem.
If you managed to solve the problem on your computer but other devices are still in trouble
(and they are connected to the same router), these addresses should be entered into the
router as well.
In case you’re interested, visit our YouTube channel for a good video about configuring
a router, and I will leave the link below.
Open the settings - Network - WAN or Internet.
Change DNS here and save the settings.
If it doesn’t help to fix the problem, try cleaning DNS cache and other network settings.
Clean cache and other network settings Launch the Command Prompt as Administrator
and run the following commands one after another, to clean the cache and network settings.
Run the following commands, one by one: ipconfig /flushdns
ipconfig /registerdns ipconfig /renew
ipconfig /release
In Windows 10, you can do it by resetting the network.
Open the router settings - Network & Internet - Status - and find Network reset below.
Click to reset it now.
After that, restart the computer and check the Internet connection again.
Install network adapter driver One more cause behind the Internet connection
problem could be missing network adapter drivers.
Although such error is quite rare in this case, it’s better to check all possible
causes to be on the safe side.
Open the Device Manager by right-clicking on the Start menu.
View the list to see if there are any devices with a yellow exclamatory mark next to them.
If there are some, it means they need to have a driver installed.
You can learn more about downloading and installing a proper driver by watching one of our videos.
Follow the link in the description.
Right-click on the device - Update driver.
Configure antivirus and firewall One more thing to trigger this error is installation
of an antivirus or configuration of the firewall.
Also, this is what happens when you set your antivirus to maximum security.
Try to disable the antivirus for a while; if the Internet connection is restored, then
it’s the antivirus to blame.
For example, Avast antivirus often interferes with Windows network settings, thus causing
various issues with Internet connections.
For example, your Internet connection is down when you uninstall the antivirus, a DNS error
appears, or the network adapter suddenly encounters problems with IP configuration.
In this case, what you need is to stop the antivirus.
If it doesn’t solve the problem, uninstall it.
An alternative is to reinstall it, but without any extra components.
Finally, the last step to take is to contact your provider about this issue.
If you tried all the methods in this video, but the error is still there, contact your
Internet service provider’s tech support and explain your problem in detail.
Quite often, DNS issues can be caused by things that only your provider can fix.
If your provider insists they have no problems at all, the only way out is to reset your
operating system.
