Working with a RDS on Windows Server 2008 R2 (terminal services) server that I have turned off IE ESC using Server Manager. When I open all programs, even those that request Internet information, I do not receive any warnings. When standard users open programs that access the Internet, they are prompted with "Content within this application coming from the web site listed..." Sometimes the programs works and other times they just crash. Users have even attempted to add the sites stated into the Trusted Sites zone. I can't seem to find the right area to modify the setting so that users are no longer prompted with this warning.
