DNS lookup failed after windows 10 upgrade

Hi Jonny,

Thank you for posting on Microsoft Communities.

I will be glad to help you with the issue you have with the computer. I understand the frustration when things don't work the way it should.

I would suggest you to clear the DNS cache and see if that fixes the issue. Clearing the DNS cache forces DNS to query a DNS server rather than using information stored in the cache.

Follow these steps:

a. In the search box, type "command prompt."

b. In the list of results, right-click Command Prompt, and then click Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

c. At the command prompt, type
ipconfig /flushdns

d. Then type ipconfig /registerdns and press
Enter

Please reply with the results, I will be glad to help you further.

Thank you.

 

repeated failure to open links

Hi,

Thanks for posting to our Microsoft Community.

DNS (Domain Name System) translates URLs into IP (Internet Protocol) addresses (and vice versa).

I would suggest you to clear the DNS cache and see if that fixes the issue. Clearing the DNS cache forces DNS to query a DNS server rather than using information stored in the cache.

Please follow the below steps and check if it helps,

• 
  Type cmd in the Search bar. Right click and open as administrator.
  
• 
  Type ipconfig/flushdns.
  
• 
  Exit and then check.
  

Please reply us back if you have further queries. We will be happy to assist you.

 

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
