In this article, I will discuss solutions to get rid of the "Error 105: Cannot resolve DNS server address" when trying to go to a website. Depending on your browser, the error may be slightly different. But the essence of the problem and solutions will be the same. The problem is that your browser doesn't open any site or most sites. At the same time, some programs can work online.

More often than not, this error appears on a single computer. And if you use the Internet via a Wi-Fi router, everything can work fine on other devices. The reason for the "Cannot convert DNS server address" message may be a change in network settings, either by the user or by some program. It's not uncommon for anti-viruses to cause this error. Just like viruses and malware. In any case, we'll fix it now. The solutions will work for Windows 10, Windows 8, and Windows 7.

But first, perform a few simple steps and checks:

  • In case you have an Internet connection via a router, you need to reboot it. Simply turn off the power and turn it back on after one minute.
  • If there are other devices connected to the router, check if the message "Cannot convert DNS server address" appears on them when you open the site in your browser. If the error occurs on all devices, the problem is most likely with your Internet service provider. You can always call support and ask. It could be something with the Wi-Fi router.
  • Maybe the Internet is directly connected to your computer. You can go to "Network Connections" and disable and re-enable the adapter "Network connection" or "Ethernet" (in Windows 10).

The most working solution is to change DNS to Google Public DNS. Also, resetting the network often helps. Read more about this in the article below.

Changing DNS to solve the error with the DNS address

Error 105 "Cannot resolve DNS server address"

We need to open the properties of the IPv4 protocol connection to the Internet and write the static addresses.

  1. Go to "Network Connections". This can be done by running the command ncpa.cpl (in the "Run" window, which you can call with the shortcut Win + R).
  2. Next, you need to open the properties of the connection through which you connect to the Internet. This can be a "Network connection", "Ethernet", "Wireless connection", a high-speed connection, or with the name of your provider.
  3. Next, highlight "IP version 4 (TCP/IPv4)" and click "Properties". Assign DNS:
  5. If the error does not disappear at once, restart your computer.
  6. You may have already had some numbers entered there. In this case, try to set it to get DNS automatically.

Reset network and DNS cache settings

If you have Windows 10, you can do everything through the settings. But you can use the method described below. In Windows 8 and Windows 7, you must run several commands at the command prompt, running as an administrator.

  1. First, reset the DNS cache by running the command:
  2. If this does not help, run the following commands one at a time:
    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /renew
  3. After that, restart your computer.

The "DNS-client" service and the problem with the DNS server conversion

You should check if the "DNS Client" service is working. To be honest, I have not yet seen a case where this error appears just because of this service. But if it is stopped, it will happen. Therefore, we need to check it.

  1. The easiest way to open services is with the command compmgmt.msc. Press Win + R, type the command, and press Ok.
  2. Next, find the service "DNS-client" and open its properties.
  3. The startup type should be "Automatic," and the service should run.
  4. Most likely, you had a service running.

Antiviruses and viruses

Think about what you were doing on your computer before the DNS conversion problem appeared in your browser. Maybe you installed something, deleted something, or configured something. This might help in finding the cause and the solution.

As for antivirus, you can temporarily disable it and check the loading of pages in your browser.

If none of the above methods helped to fix the error, it is quite possible that it was caused by a virus. Run an antivirus scan on your computer if it is installed. You can also use free antivirus utilities. For example, Dr.Web CureIt!, Kaspersky Virus Removal Tool, and others.

Hope we answered how to fix the DNS address bug and your favorite sites started to open. But if the problem remains, you can always contact Howly to get the best consultation and solve your problem within minutes!
