Windows 10H2 DNS Problem

[mahala99]

I have an issue with the Windows 10H2 Feature Update which causes some quite specific DNS-related Internet access problems.

Following the update I cannot load certain web pages and e-mail access doesn't work. Specifically, google.co.uk works but bbc.co.uk doesn't. When I ping www.google.co.uk I get a response with an Ipv6 address; when I ping www.bbc.co.uk I get an IPv4 address but no response. Other IPv4 addresses give the same problem.

This happens regardless of whether I am connected via Ethernet or wireless. Changing my DNS servers to Google doesn't make any difference.

I had much more serious Internet access problems last year when the2004 Feature Update was installed. These prompted me to back out the feature update and fix my release to 1909 via the Registry. Unfortunately 1909 is now out of support and Microsoft started forcing the 20H2 update on me earlier this month. I have now backed it out twice and currently I have delayed all Windows 10 updates until June in the hope that I can find a fix in the meantime.

Any help with solving this problem would be appreciated.

Sorry, I meant Windows 20H2 not 10H2. Apologies for that

My period without Windows 10 updates ended earlier this and again Microsoft forced a 20H2 Feature Update on me. As expected I got the same Internet access problems. That is no DNS resolution of IPv4 addresses which also affected Mailbird which I use as my preferred e-mail client.

As suggestions to how I can fix this Windows 10 problem would be appreciated.
