Sometimes we publish applications on the web front end, but we also want to give clients the option on launching an RDP session directly from the website.
For doing that we need to change a registry and reboot the server:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\CentralPublishedResources\PublishedFarms\<collection>\RemoteDesktops\<collection>
Change ShowInPortal from “0” to “1”.
