Windows 10: DNS ISSUES STARTING 11/13/2018

I work for a local ISP and we have had 100's of Windows 10 users calling in with "DNS server not responding" when we run troubleshooter on their PCs.


I am referring them to Microsoft as this is not an issue with their internet service but was wondering if the recent update caused this, why it is only happening on some PCs, and any other info would be greatly appreciated.

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

DNS server causing problem

Hi Andrea,

DNS is a server that translates websites' addresses so that browsers can connect to them. If the addresses become outdated or the server has issues, problems and DNS errors occur. For us to provide an accurate solution, we would need you to answer the following
questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to your device before this issue occurred?
• Are you experiencing the same issue regardless if you are trying to be connected to a wired or wireless connection?

For initial troubleshooting, we suggest deleting the DNS cache. This can refresh the DNS files and settings on your PC. Follow these steps to delete the DNS cache:

• Using Search type Command Prompt.
• Form the search results, right click on Command Prompt (Desktop app) and then choose Run as administrator.
• In the Command Prompt window, type ipconfig /flushdns and then hit the Enter key.
• Once done, restart your computer and then check if the same issue persists.

We are looking forward to your response.
