Windows 10: Changing DNS settings breaks internet connectivity

Hello!

I am running Windows 10 version 20H2, build 19042.685.

When I try to configure manual DNS under my adapter properties, DNS no longer resolves and my internet does not function properly. Moreover, when I use a VPN service, the internet does not function, presumably due to the same issue.

Some notes:

• This is not related to my network. This machine has been taken to several different networks, and the issue has persisted on all of them. Moreover, I have configured severalother devices on the SAME network as the Windows 10 machine, all of which can use custom DNS or VPNs with ease.
• This issue does not persist if I set my DNS to configure automatically.
• The DNS server I am trying to use is not blocked on my network. Again, I have tried this on several networks so this should not be a concern, but I specifically tested it on other devices and made certain that any and all DNS servers I was attempting to use were in fact not blocked on the network.

Troubleshooting steps already attempted:

• Disabling antivirus Bitdefender
• Uninstalling antivirus
• Restarting several times
• Trying to set custom DNS on WiFi as well as Ethernet adapters internet works on neither when custom DNS is configured
• Resetting TCP/IP using netshell "netsh int ip reset"
• Flushing DNS cache using "ipconfig /flushdns"
• Disabling IPv6
• Booting into Safe Mode with Networking and attempting to make DNS changes there
• Running Network Troubleshooter it could not identify the problem

Any further information on reasons this might be happening as well as possible solutions would be greatly appreciated!!

See screenshot for a visual representation of how I am changing my DNS resolvers. On the second page "Internet Protocol Version 4 Properties", I choose "Use the following DNS server addresses" and enter in my DNS resolver.

dns probe finished no internet


Hi Oxide,

After some trial-and-error testing of all suggested fixes, which I found over the internet, here’re what worked for me to solve "DNS Probe Finished No Internet" issue and might work for you as well.

Method 1: Change Default DNS Address to Open DNS

Here all you have to do is change your default automatically obtained DNS server addresses to open DNS or Google DNS. To do this, follow below mentioned steps:

Step 1: Right click on Network icon located in Windows Task Bar Menu.

Step 2: Click on ‘Open Network and Sharing Center.’





Step 3: Click on Local Area Connection with whom who are presently connected and click onProperties.

Step 4: Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on Properties.

Step 5: Now in newly opened windows, select the radio button that reads ‘Use the following DNS server address:’

Step 6: Now in the ‘Preferred DNS Server’ box type in 208.67.222.222 and in ‘Alternate DNS Server’ type in 208.67.220.220.

Step 7: Now check the box that says ‘Validate settings upon exit’ and then click on OK. That’s it.

DNS SERVER NOT RESONDING

Hi Rita French,

This issue often occurs when the DNS settings are incorrect. I suggest you to perform the following methods to troubleshoot the issue.

Method 1:

I would recommend you to change the Preferred DNS server and check if it helps.

• Press Windows + R keys to open Run window, type
  ncpa.cpl and press Enter.
• Right-click on the connection that you use for the local connection, and then click
  Properties.
• Click to select Internet Protocol Version 4 (TCP/IPv4), and then click
  Properties.
• In the Internet Protocol window, let's change the Preferred DNS server to
  208.67.222.222
• Click OK twice to complete the modification.

Note: If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220.

Method 2:

If that does not help, try to flush the DNS. Follow these steps below.

• From Start screen, type Command Prompt.
• Right-click on Command Prompt and choose Run as Administrator.
• Type: ipconfig /flushdns and press Enter.

Note: The ipconfig /flushdns command provides you with a means to flush and reset the contents of the DNS client resolver cache. During DNS troubleshooting, if necessary, you can use this procedure to discard negative cache entries from the cache, as well
as, any other dynamically added entries.

Hope any of these methods help!

Kind regards,

Leon
