Hi All!

My query unfortunately was not resolved in Microsoft Community and a tech guy advised to post it here.

Notebook in question: HP Pavilion 17 K6Y34EAW (17,3"/AMD A8/4GB/1TB/Windows 8.1)

In first 2 months the machine performed fine but after one of the MS updates DNS errors started to come up, for instance:

DNS_PROBE_FINISHED_NXDOMAIN

DNS_PROBE_FINISHED_NO INTERNET

EER_CONNECTION_TIMED_OUT

EER_QUIC_PROTOCOL_ERROR

It takes quite long to download a website and often it appears with reduced content, broken images, etc.

Actually only Chrome classify the errors as DNS-related, the other browsers such as Mozilla, IE8 or Edge just say "Server not found", "This page can't be displayed" or "Hmm, we can't reach this page" respectively. So you now may guess W10 doens't resolve the problem.

What I tried and what didn't help or provide only temporary solution:

1) ipconfig/release - /flushdns - /renew (all run as admin)

2) netsh int ip reset c:\resetlog.txt (run as admin and then reboot followed)

3) talked with internet service provider (everything is OK on their side)

3) also tried wired connection (Ethernet) but no luck (currently using wi-fi)

4) tried to use IP address advised by service provider

5) tried to use preferred/alternative DNS server: 8888/8844

6) switching off firewall and antivirus

I am now quite sure it was W8.1 and currently W10 that is faulty because the old Lenovo running with XP doesn't produce DNS errors.

Looking forward to your feedback, guys!

Cheers,

Viktor

As a simple test, you might try using the OpenDNS servers (rather than the ones provided by your Internet Service Provider).

That way you'd know for certain if the problem is at "your end" or not.

Hi,

As your state, it is a strange problem after you attempt so many feasible ways to troubleshoot but failed.

In addition to your troubleshooting ways which you have attempting, I suggest you can try another three ways to troubleshoot the issue.

Firstly, have you used Windows troubleshooter to solve the problem? If not, just open Control Panel > Troubleshooting > Network and Internet > Internet connections. You can use the troubleshooter to troubleshoot the issue.

Secondly, reset your Internet Explorer settings to exclude the possibility of address settings issue.

Also, if you are sure the problem is occurred once you installed the Windows Updates, I suggest you can perform System Restore to make your PC back to the point which use normally.

Wish you will troubleshoot the issue smoothly.

Hi! For some reason I cannot access the modem/rooter but once I have managed to do it, I will give you a feedback. Thanks for your advise!

Hi Simon! Thanks for your reply!

1) Yes, I've tried it several times. No findings.

2) I tested both IE and Edge as I mentioned in my original email. As you advised, I've reset the settings in IE and will give you a feedback on the result.

3) See no reason to restore the system cause I have recently installed W10

Cheers,

Viktor
