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.
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.
Update fixes Windows 10 bug that ruins your internet connection
• 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.
p.s. How can I get email notification if someone answer from this new forum?
