DNS cache problems

Hello, IvoMI

Welcome to the Microsoft Community.

It sounds like you're experiencing a troubling DNS caching issue after the recent update, and it's great that you've checked for basic issues like cables and malware scanning. We can continue to troubleshoot potential causes and solutions.

First, you can start by heading over to your computer's brand's website to download the corresponding new NIC driver, which can sometimes have compatibility issues with new system versions.

After that, refer to the following steps to reset your network environment:

A. Reset the network

1. Search for CMD, open and find the command prompt (, to run in administrator) mode
2. In the pop-up command box, enter the following commands (each line after the completion of the run enter the next)

ipconfig /release

ipconfig /renew

ipconfig /flushdns

ipconfig /registerdns

netsh int ip reset

netsh winsock reset

netsh winhttp reset proxy

3. Restart the computer to see if the problem can be solved.

B. Reset Network Settings

Tap windows+R, type inetcpl.cpl, open Internet Options, click Advanced, and check “Use SSL 3.0” and “Use TLS 1.0”, “Use TLS 1.1”, ‘Use TLS 1.2’, reboot the computer after the application to see if the problem can be solved.

C. Reset Proxy Server Settings

Click windows+R, type inetcpl.cpl, open Internet Options, click Connections, click LAN Settings, check whether the Proxy Server column is checked, if so, uncheck it and click OK, restart your computer after applying it to see if the problem can be solved.

D. Change DNS

1. Click windows+R and type ncpa.cpl.
2. Click on the name of the network you are now connected to, open the Network Status window, click Properties, and then double-click Internet Protocol version 4 (TCP/IPv4) in the Network Properties window.
3. Manually set the DNS servers to “4.2.2.1” and “4.2.2.2” and restart the computer to see if the problem can be solved.

You can try it out by referring to the steps above, and after that, give some feedback and I will further support you.

I changed my proxy settings and it now works fine. So search "proxy" in settings. Select change proxy settings and then just toggle the proxy server button to off and it's all back up and running.

I also changed the dns settings to the recommended. I haven't yet tried without doing that.

Hi TLS_885,

I am having the same problems as of today.

Says problem with DNS cache.

I follow all steps of advice, and when computer is reset, it says I have a connection, but nothing will connectcand it reports the DNS problem again.

Did you find a solution?

Cheers

I have the same problem. I tried the solutions described but no sucess.

Hi Bobhe,

Thanks for the advice. I am currently doing some research so that I understand every command before I try anything.

I have found some interesting things.

When running the Troubleshooter, the message that there is a problem with the DNS cache quite often changes to 'You are connected to the internet' after a few seconds.

Also, playing a game of MS Solitaire establishes an internet connection. I suppose that the game does that so that it can display ads.

Finally, network status (in Control Panel) does not always show the correct status (as in 'connected') even though the connection is OK.

Kind regards,

IvoMI
