Still not fix ‘no internet’ connection bug in Windows 10 2004 (OS Build 19041.546)

Question

I ever posted this issue on MS TechNet and someone told me that it’s a bug on version 2004 from Microsoft. Then nothing can do.

So I tried this.
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet”
Modify “EnableActiveProbing” and change the value from ‘0’ to ‘1’.

Result: Not help. It only works successfully for every several computer start.

Recently, I find this bug is fixed from below info.

• Addresses an issue that might prevent applications from opening or cause other errors when applications use Windows APIs to check for internet connectivity and the network icon incorrectly displays “No internet access” in the notification area. This issue occurs if you use a group policy or local network configuration to disable active probing for the Network Connectivity Status Indicator (NCSI). This also occurs if active probing fails to use a proxy and passive probes fail to detect internet connectivity.

After upgrade my PC to OS Build 19041.56. The issue is not solved. It only works normal for every several computer start.
If 'no internet' issue happens, I can't syn email normally on Outlook / Open onedrive files from Excel / Spotify app failed.

Please help.

p.s. How can I get email notification if someone answer from this new forum?

Answer 1

Hi ,

Thanks for your updating. Have you checked HKLM\Software\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator to see if there any registry keys?

Find a solution. If I connected Surfshark VPN and access Internet, then disconnect VPN. It will return to normal. 'No internet' issue will be disappeared.

Good to hear that you have solved this issue by yourself. In addition, thanks for sharing your solution in the forum as it would be helpful to anyone who encounters similar issues.

In addition ,if there is no specific event/error about the problem, it is hard for us to analyze root cause from forum support level . In such case, we need to trace network monitor to find any clues. Unfortunately, analysis of network traffic is beyond our forum support level. If the issue is urgent and you want to find the root cause, I would suggest you open a case with Microsoft where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.

Answer 2

Hi ,

I haven't install kb4577063 yet. In my lab, if the value of EnableActiveProbing is 0, then NCSI icon in system tray reports "no internet". As the picture below:

If I modify the value of EnableActiveProbing from ‘0’ to ‘1’ and restart the machine, then everything will be fine.

Result: Not help. It only works successfully for every several computer start.
After upgrade my PC to OS Build 19041.56. The issue is not solved. It only works normal for every several computer start.

What did you mean about it only works normal for every several computer start? Could you please clarify more details? It would be helpful for us to identify the problem if you could upload the screenshots or clarify more details.

Answer 3

Here is my screen capture. FYI.

This parameter EnableActiveProbing is set to 1 for one month. Just wonder why still not fix after OS Build 19041.56 is applied.

Sorry for my bad english.
I mean when it shows 'no internet' this time. Then will be fixed after restart again or may need to restart several times.

Any idea? Thanks for your help.

Answer 4

Hi ,

In order to get a more concreted idea of this issue, I would appreciate your help to collect the following information for further troubleshooting:

1.Did the problem occur on all windows 2004 OS Build 19041.56 machines? Or just occurred on certain machines?

2.Does restarting the Network Location Awareness (NLA) service fix the issue?

3.Are proxies or hotspots present in the problem environment?

Please make sure HKLM\Software\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator NoActiveProbeshould either not present, or value must be 0.

Make sure passive probing be enabled as well. In case active probing fails, passive probing can also detect internet unless it’s disabled by GPO. Check below to make sure you didn’t disable passive probing. If it is, enable it and test again.

Group Policy path: Computer Configuration\Administrative Templates\Network\Network Connectivity Status Indicator

setting: "Specify passive polling" = Enabled, uncheck "Disable passive polling"

This GPO setting can be also confirmed from this registry key:

HKLM\Software\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator

In addition, when the issue occurs again, please run the PowerShell cmdlet of Get-NetConnectionProfile.

Example of good connectivity:

If for any of the interfaces IPv4 or IPv6 connectivity indicates “Internet” the machine connectivity is INTERNET, and in that case the issue should not be an NCSI problem.

Candy
