No NCSI pop-up behind a captive portal RRS feed

  • Question

  • Hi everyone,

    I'm using a PC with an up to date Windows 10. I'm connected to a captive portal network.

    The DNS resolution of the URI www.msftconnecttest.com works and the GET of the URI "http://www.msftconnecttest.com/connecttest.txt" is redirected to the portal captive login page.

    However, the NCSI shows "Internet Access" and do not display the pop-up inviting the user to login himself to access Internet.

    Can you please explain me why ?

    Thanks in advance for your help.

    Benjamin

    PS : sorry for my english.

  • Hi,

    Thank you for your answer.

    Can you please explain what you mean by "AD interception software" ? 

    I check the link but i didnt learn anything new and there is an error as the web page accessed by the NCSI in Windows 10 isn't www.msftncsi.com but www.msftconnecttest.com.

  • Hi,

    Thanks for your reply.

    These  Advertisement interception software may block pop-up page.

    Please try to disable these two Advertisement interception software and check whether the issue still exist.

    Or you can try to set the Internet Explorer as the default browser and check whether the issue still exist.

    Best Regards,

    Eric

  • Hi,

    Thanks for your reply.

    I have tried to set Internet Explorer as the default browser but the NCSI didn't showed the pop-up nor autoaticaly open Internet Explorer to display the captive portal login page.

    I also have disabled AD-Block on firefox (previous default browser), and i have got the same results.

  • Hi,

    Thanks for your reply.

    This issue might occur, when some of the system files got corrupted.

    I would suggest you to try the below methods and check if it helps.

    Method 1: Perform System File Checker (SFC) scan and check if it helps.

    System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

    To perform SFC Scan, refer to the below link:

    https://support.microsoft.com/en-us/kb/929833

    Method 2: Run DISM commands and check if it helps. 

    Deployment Image Servicing and Management (DISM) is a new command line tool that you can use to service a Windows image or prepare a Windows PE image. The DISM tool replaces the Package Manager (pkgmgr.exe), PEimg, and Intlcfg tools. DISM consolidates the functionality found in those three tools, as well as delivers new functionality to improve the experience of offline servicing.

    Follow the steps to Run DISM Commands:

    1) Press Windows + x on your keyboard.

    2) Select Command prompt (Admin) to open Administrator Command Prompt .

    3) In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:


         dism.exe /online /cleanup-image /scanhealth


         dism.exe /online /cleanup-image /restorehealth

     

    Best Regards,

    Eric

    The solution above did not solve my problem. FYI, it's a fresh install of Windows 10.
