[German]Strange behavior: Windows 10 reports, that no Internet connection is available. However, users can surf the Internet with a web browser and viee web pages without any problems.
Blog reader Martin U. drew my attention to the problem, which I take up in this blog post, by mail with the subject Internet despite the display “No Internet” in WIN10 (thanks for that).
‘No Internet’ error message, although surfing works
Background is this Microsoft Answers forum thread from January 30, 2020, where a user writes:
DNS manually assigned – now win10 thinks there’s no internet. But it works while surfing.
As soon as I enter manual DNS server addresses in the IP4 protocol of the network adapter, WIN10 believes after restarting that there is no internet connection.
Bottom right globe with prohibition sign. Spotify reports offline etc. But I can surf the internet very fast with all browsers.
I set the DNS server address back to automatic, restart, Internet is displayed and everything works.
The manual DNS servers are much faster, so I would like to use them.
My question. Why does WIN10 claim that there is no internet with manual DNS servers or how does it recognize manual DNS addresses?
The user was a bit perplexed at this point and asked if anyone else had a trick / tip for him.
Blame a Registry entry
In the forum thread, the user later reported and suspected that probably a registry entry in the key:
will cause this behavior. And on January 29, 2020 there was a resolution that the DWORD value EnableActiveProbing = 0 was set. This deactivated the respective test of Windows on manually set DNS addresses.
When the registry value was set to EnableActiveProbing = 1, manual DSN server addresses could be entered after a restart and the Internet display worked again. Maybe it helps someone.
