TS 2012 R2 RemoteApp - .RDP publisher not trusted

Hi,

Like this post here http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2012/Q_28110025.html, I am also getting crazy and am not able to solve my problem.

On a TS 2012 R2, I have created from CA an internal certificate and assigned it to RD Server (see RDP-Certif.jpg).
So internal computers are not getting the "untrusted SSL certificate" error when accessing the RDWEB.

But when trying to launch an App, I am getting the error: "Publisher of this RemoteApp can't be identified"(see error-client.jpg) and this is annoying.

I have pushed by GPO the SH1 thumbprint without taking the first blank character (space). It is well pushed to client (see RDoP-client.jpg) but issue remains.
I have even typed the thumbprint manually and in capital letters of course, BUT NO SUCCESSSSSSS !!

I do not understand why the publisher is still blocked while I clearly see its thumbprint in the trusted publisher policy.

Would you have any idea ??

Thank you

As one of your screenshots shows, you have not configured the RDCB publishing certificate. Thus the .rdp files are effectively being self-signed at this time, which is inherently untrusted.
