Internal website asking for authorization to open windows explorer RRS feed

  • Question

  • Hi,

    I have two brand new server 2016 standards.Running Windows 10 1809 at this time.

    One server hosts a VERY basic intranet site where people on the shop floor can (among other things) open PDF files of blueprints from a folder on the intranet share (menu link is the folder name)

    A collègue recently brought to my attention that when they try to access these blue prints, they get a prompt "Do you allow this website to open an application on your computer" (Windows Explorer) (translating from French may be inexact)

    This is very annoying for them and I need to stop this prompt.

    I've tried creating gpo to put my intranet server in the intranet zone, I'm not sure if this is an IE issue or a UAC issue.  I thought I had UAC turned off actually but I see it is now on the highest setting on my own computer, did the GPO settings for this change at some point with a Windows version or when I moved from Server 2012 to 2016?

    What do you think I need to do to stop this prompt?

  • Hi, thanks for your reply.

    I already have it in intranet zone in Default Domain Policy GPO, isn't that better than trusted sites?

    Entrez les attributions des zones ici.* 1* 1
    file://* 1 1
    https://srv-008-vm/RDWeb/Pages/fr-FR/Default.aspx 1

    If I change from IP to server name, it does not prompt, but it opens up a web directory page with the file names and not file explorer.  My users are shopfloor people and so they don't understand how to navigate this way.

    I do see underIE\Internet Options\Security\Trusted Sites that it asks for an https server. not sure if Something changed between server 2012 and 2016 regarding this

  • Hi, thanks but I'm using GPO to control these settings, the site is in the intranet zone(see my reply to another poster above).  I do need to do whatever I do by GPO.
