I'm having a devil of a time trying to figure this out. We are preparing to roll out Windows 2012 RDS; we are going to be using published RemoteApps to our users in their web browsers. However, the first time a user accesses the site, they are prompted to run an Active X control "Microsoft Remote Desktop Services Web Access Control". I am trying to set our Group Policy to allow the automatic installation of this particular Active X control. And I can't seem to figure out what settings to change.
I've looked at "Computer, Administrative Templates, Windows Components,Active X Installer Service". I enabled "Approved Installation Sites", and put in the URL of "https://rds-server-FQDN/RDWeb", and value "2,2,1,0". This should allow the installation (I thought) of this control. Turns out, the user is still being prompted. Anybody know what else I have to enable, so my user isn't prompted to install the Active X control, and it just installs automatically? Just the controls from my one site should be allowed. Thanks
