Windows 10: Loss of internet - DNS Issues

Several computers have been loosing internet.


The computer diagnostic says its a DNS issue but only a restart fixes the problem. All the other computers will be fine during the time one is down.


It appears to be online when looking at the icon in the bottom corner of the screen but when ever you try and browser the internet it says DNS issue.


Some computers have this reoccurring issue where others have only experienced it once.


How can I fix this when it happens and how do I prevent it?

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
