Windows 10: VPN or manual DNS resolver settings break internet; Windows 10

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

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

Windows 10 DNS leak

No, went with a different 3rd party suggestion. Works better. I'm reliant on others for my tech needs that way.

 

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.

 

Preferrence of DNS servers from VPN issue (DNS Leak)


Hello,

when I connect to VPN, I receive DNS servers, but windows primarily uses DNS servers configured on my LAN connection (checked with nslookup). This is problem when I am accessing same hostname, which has internal IP in VPN.

I tried to change network adapters order in ncpa.cpl, but it does not seem to be working. It displays still same order despite of how I change it and confirm with OK.

Checking in regedit, HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Linkage\Bind,
after connecting VPN, one entry gets added on top of the list, I assume that is dialed connection.

Setting DNS servers manually in VPN does not work, I am unable to edit procotol settings in VPN connection.

Anyone have some solution for this ?
