Got an rdp file that the Customer wanted to publish as an application in Citrix. You could ask why, but that's what they wanted. It is connected to another provider who has Microsoft Remote App, and my Customer want to work with this inside the Citrix Environment to be able to reach all resources from here. So, first I tried to publish mstsc with the supplied rdp file as argument - but it will not start when running in a seamless session. However, it starts up when launching it from a Published Desktop. To avoid to publish special Desktops only for this application, I started examine the provided rdp file. I first stumbled by the setting: remoteapplicationmode:i:1 Wondered if I could change that to 0, making it an ordinary rdp-connection? Nope, since the last part of the file includes: signscope:s: signature:s: making sure you cannot alter these settings. If you do, mstsc will report that the rdp file is broken. But what if I remove these two settings from the rdp file?
