[2004, 20h2] No internet access

[Android2408]

Since moving up to 20H2 in our school we have an issue with most machines showing "no internet access" disconnected icon, this now stops outlook and adobe from working properly due to them thinking that you are offline.

 

Thanks

There is a reg hack you can do to stop this

 

[HKLM\Software\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator] , set the registry key of NoActiveProbe to

 

Then reboot

This is controlled by a few settings that may have changed, or have started respecting something that was set before.

 

Check that an example machine has the following settings under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

 

 

 

If those are set as per the image then the problem is either a bug in 20H2 which some people have reported, or it is an issue with proxy detection, or something your ISP is doing.

Post 1703 I believe this breaks the connectivity indicator such that it will never show internet which is not what the OP wants! The official fix is to point the settings in my post to something internal to bypass the external connectivity check.

Sorry JCX500 but that doesn't work (last long anymore). You will need to allow unauthenticated internet access for devices to the IP/URL:http://www.msftncsi.com/ncsi.txt and http://ipv6.msftncsi.com/ncsi.txtA request for DNS name resolution of dns.msftncsi.com should resolve to 131.107.255.255 / fd3e:4f5a:5b81::1if you're using a proxy this set at login then this will be a problem, but if your devices can see the internet at the Windows login prompt - just specifically to the above, then you will be fine, or set you firewall to allow this access regardless of proxy presence.Its the only lasting solution.

 

GoodluckThanks

Thanks everyone, got this fix of someone and so far seemed to have sorted on the machines I've tested so far (fingers crossed)

 

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 Indicatorsetting: "Specify passive polling" = Enabled, uncheck "Disable passive polling"Locate gpedit.msc. The setting for gpedit.msc within "Computer Configuration -> Administrative Templates -> Network -> Network Connectivity Status Indicator".Enable the 'Specify Global DNS' setting.
