"No Internet Connectivity" warning sign on Network icon but Internet works fine.

Question

_{Monday, March 12, 2018 1:41 PM | 1 vote}

Hello, 

We've got three Windows 10 Pro laptops in our organization and all three show the "No Internet Connectivity" warning sign on the network icon but the internet and all network services work fine. The three laptops are joined to our domain. When the laptops connect to public WiFi networks or home WiFi the "No Internet Connectivity" warning sign does not show, it only shows when the laptops are connected to our domain network. I have tried flushing DNS, resetting the TCP/IP stack, and nothing seems to work. 

The rest of the computers in our organization are Windows 7 and none of them show the "No Internet Connectivity" warning sign. 

Any help or guidance is greatly appreciated!

You were right the culprit was a Group Policy. After you mentioned it, I started scouring through our GPO settings and found the following:

Computer Configuration->Policies->Administrative Templates->System->Internet Communication Management->Internet Communication Settings->Turn off Windows Network Connectivity Status Indicator active tests.

This setting was Enabled. According to your link if the NCSI is turned off it will cause the yellow warning sign to show on the network icon in the system tray. After I disabled that setting and updated the GPO, the warning signed disappeared. 

Thanks for your help!

Not sure if you have seen this https://www.ryadel.com/en/yellow-triangle-over-network-connection-status-how-to-fix-it/

but it explains more how that check works, so may help. It also links to some MS articles. To me most likely caused by some Group Policy settings affecting Windows, or the Windows Firewall being on the Domain profile when connected to the domain. Have you tried turning the firewall off as a test?

Thanks for your reply. I read the article that you linked and I understand now how the network check works and what its purpose is. 

The Windows Firewall is disabled on the domain network profile no the Windows 10 laptops. That is one of the first things I tried in my troubleshooting efforts but the yellow warning sign still shows up. 

I'm out of ideas.

Well thinking you have check the services mentions, and they can access the name and txt, does that all pass on an affected machine?

Well still thinking something group policy is affecting it on Windows 10 laptops. Can you create an new OU block all inheritance and load a new laptop from an ISO and put it that OU before the first reboot to put it in the domain?

This may have to do with the DNS configured on the network adapter, change it from 127.0.0.1 to the local IP address instead and it may resolve the problem.

Also, disabling IPv6 is a workaround.

This blog entry has some helpful information: The Network Connection Status Icon

https://blogs.technet.microsoft.com/networking/2012/12/20/the-network-connection-status-icon/

In this blog, there is a statement:

Since the connection status icon can only show the status for one connection it will aggregate the individual statuses and display the most limited connection. Therefore if more than one network adapter is present, but only one probe succeeds, Windows will still report “Limited Access “and indicate a Local only status. In Microsoft DirectAccess, NCSI is also used for Inside/outside determination (Outside corporate network or Inside corporate network). To do this the NCSI process tries to communicate with the I/O (Inside/Outside) server using an HTTPS query.

Had the same problem.  Booted into safe mode with network then rebooted back into windows.  Problems was solved.

Yes!!!
After weeks of trying tons of solutions, "safe mode with networking" is the only thing that worked! Thank you so much!
