Windows 10: Network Icon Yellow Triangle - Windows 10 v1803

OS: Win10 x64 - v1803
Dell workstation Optiplex 780, 7010
Onboard network - Intel(R) 82567LM-3 Gigabit Network.

Problem: Yellow network icon but still able to surf the interent (webpages), but Internet icon shows the domain name but Not connected. Can ping out to external sites as well.

Started to have this issue with a few of our Dell workstations. The dreaded yellow triangle icon on the network icon has appeared, with users still able to surf the internet via websites and download applications.

All the workstations are within a domain, DHCP and DNS, and each Ethernet is connected via IPv4 to automatically get the IP address from the range, no static IP addresses are used, so with the Network & Sharing Centre - under the Properties of the Ethernet adapter, IPv4 properties has Obtain an IP Address automatically as well as the DNS server address.

When i click on the network icon (see image1) the NIC is connected to the Domain but No Internet is shown.
On a few workstations if i open a CMD window as Admin, and pinged a few sites the icon returned to the default (Connected to the domain and connected to the Interent). But some workstations refuse to clear the icon.

I have done the following.

1. Removed the network driver from within device manager - rebooted and reinstalled the driver from the Dell website.
2. CMD (as admin) - Pinged the following address ok BBC - Home, Microsoft Corporation.
2. Removed the workstation from the domain, removed the OU from AD and then rejoined the domain on the workstation - no change in the network icon.
3. On the workstation - ran the following commands in CMD. ipconfig /release , ipconfig /renew, ipconfig /flushdns - rebooted - no change in the network icon.
4. Within RegEdit deleted the following:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Nla\Cache
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Signatures\Managed\
5. within Local Security Policy - Network List Manager Policies - the Domain is listed.
6. Services - Disabled the following services - Network Location Awareness, Network List Services - rebooted - still no connection. Set these services to automatically to start again. These were already started before.
7. Rebooted into Safe mode - Network icon has cleared the yellow triangle and states connected to the Internet and the domain.

So racking my brain over this one any thoughts, thanks in advance.

network shows yellow triangle but network works

My windows 10 computer showed a yellow triangle in the network icon. It seemed that there was no network connection but there was. All non Microsoft programs worked fine.

After 4 hours of sweeting I found out that I had to change a registry entry

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

and then the Triangle disappeared. I'm using a wired connection.

The problem is that the windows updates doesn't work, when there is a yellow triangle. So without knowing your computer is not safe anymore, because there is some strange network check.

The question for me is why there is a network check which seems unreliable.

Kind regards

Yellow triangle on unplugged LAN icon

Just after updating to Windows 10, version 1809 I noticed that LAN icon when the LAN cable and wifi not connected yet appears as the network cable is connected with a yellow triangle on the icon.

troubleshooting gives unidentified problem.

internet connection when cable is plugged or through wifi works well.

is this the normal appearance of LAN icon when not connected to internet?
