Allow Network Connectivity Status Indicator (msftncsi.com) #8

Closed crazy-max closed 8 years ago

crazy-max commented 8 years ago

Windows check a Microsoft site for connectivity, using the Network Connectivity Status Indicator site.

NCSI performs a DNS lookup on www.msftncsi.com, then requests http://www.msftncsi.com/ncsi.txt. This file is a plain-text file and contains only the text Microsoft NCSI.
NCSI sends a DNS lookup request for dns.msftncsi.com. This DNS address should resolve to 131.107.255.255. If the address does not match, then it is assumed that the internet connection is not functioning correctly.

If you want to implement your own NCSI, check this link More info : https://technet.microsoft.com/en-us/library/cc766017%28WS.10%29.aspx

Sorry that I have to revive this one, BUT in order to get the MS Connectivity Indicator to behave we would need "dns.msftncsi.com" unblocked too :( (its included your extra.txt list and can cause issues)

Sidenotes: 1# THANK YOU FOR THIS PROJECKT! 👍 🥇 2# I hope you are okay with ppl using your blocklists as pi.hole blocklists too, as this error kind of originated from me using them for that purpose. (sorry if you are not fine with that :-( )

Hi @h1dden-da3m0n, extra rules must be used carefully. Some domains are "required" by third party applications on Windows (Skype, Live, MSFT Connect Test, etc...). But you can use our custom NCSI probe : https://github.com/crazy-max/WindowsSpyBlocker/wiki/appTelemetryNCSI And thanks for your support :)

I just discovered this issue with the www.msftncsi.com and my no connectivity internet tray icon on Windows 10 v1809. Previously I used another Windows build and I didn't had this problem.

I applied the custom NCSI probe and when I test it I have internet but my internet icon is with the no internet message status.

The only way to fix this icon is when I remove the entry www.msftncsi.com from the host file.

@h1dden-da3m0n @ribatamu I was able to reproduce your issue. @ribatamu Can you create a new issue about this please ? Thanks
