Windows 10 says I have no internet connection, but I have.

I am running on Windows 10 Enterprise, Version 2004, OS Build 19041.264.

I recently changed to the Windows Insider Program and updated Windows. In the taskbar, the Wi-Fi icon shows No Internet Access, but I have a stable internet connection wirelessly (Ex: I can browse the internet, ping IP Addresses, etc.). Another problem is when I try to open Cortana it also says that I have no internet connection (By the way, I can also open Microsoft's website).

As I know Windows checks internet connectivity with this URL: http://msftconnecttest.com/connecttest.txt. But this gives Error 404, File Not Found. Maybe it is because of this?

If you know the problem or an answer, please help. Thanks!

Hello, use Registry Editor, go to: 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

and modify: EnableActiveProbing

then change "Value data" from "0" to "1"

and restart your computer

The proper one is

"HKLM:\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator\” -Name UseGlobalDNS -PropertyType DWORD -Value 1 -Force

But the more appropriate way to do this is not through registry directly, but through group policy config:

    I'm not sure what you're specifically claiming here, but reviewing the 6-month old post you're replying to, user ДмитроЖелябін is indicating the proper value for registry setting EnableActiveProbing, value = 1.

    And this advice is correct. That IS the correct value and it should not be changed.

    There's no bug here.

    Wrong again --- why is microsoft pinging it's own site to -determine network connectivity- is beyond dumb, it is dishonest.

    * if you are locking down your systems to ONLY connect to certain sites, then the micro soft of internet connectivity will fail miserably.

    Rather than say "you are not connected to the internet, which by the length of this thread you know is a lie, why don't you -say- what part of the connectivity test is a lie. Or give the user the option to say "I really am connected to the internet, you are are?" (because how you check is flawed city).

    As others have mentioned:

    • it fails when you don't have Automatically detect DNS Server enabled. Why should microsoft care. If they can connect to something , they can. If they can't, they can't. Why is the OS determining, by DNS probes and Web Probes to itself, if it is connecting to the internet. And that the fix is to use google should tell you something.

    I work for Microsoft and am a SME for the NCSI component.

    NCSI pings it's own server on the internet because that is a trusted server and a response from it is trustable proof that the client machine can reach the Internet.

    If you are locking down your own systems to only connect to certain sites then unless you are unwilling to open up your proxy for NCSI probe server contact then you have the option of hosting your own NCSI server internally.

    The reason this connectivity logic of NCSI is necessary is so application developers don't have to reinvent the wheel and create their own homegrown network testing functions to avoid sending out network packets that would timeout otherwise. NCSI is a provision of the OS to do this work for them. But if a customer is locking down their enterprise against reaching the public Microsoft internet probe server than they are configuring against best practices.

    And these best practices have been publicly documented for a long time

    Connection endpoints for Windows 10 Enterprise, version 1903 - Windows Privacy | Microsoft Docs

    This is also documented here for Teams:

    Prepare your organization's network for Teams - Microsoft Teams | Microsoft Docs which cites the infamous 13.107.4.52 address which must be reachable,

    NCSI cannot give a simple answer for why the internet probe server is not reachable due to the many possiblities including:

    • Split tunnel VPNs misconfigured to force the NCSI probe to the corporate network instead of out to the internet
    • Misconfigured DNS servers or DNS clients resulting in not correctly resolving msftconnecttest.com or dns.msftncsi.com.
    • Misconfigured proxies
    • Firewall blocks
    • Misrouted probes to get to the enterprise edge router
    • Third party software that intercepts DNS queries on the loopback interface (which we have a GPO to get around).
    • And many other things.

    "And that the fix is to use google should tell you something."

    It tells me that whatever DNS server was not allowing the probe through before they changed to Google is misconfigured.
