We have a client who uses this and it all works just fine. Regarding the 'workstation setups' do you know, did the IT dept roll out the .msi installer? That is what we had setup, the user clicks on the MAS Icon and it launches the RDP session in the background then renders the screens on your Win7 PC's. That said, the PDF and all other pieces need to be fully working on that Terminal Server. Also agree, test in a native Terminal session that @JohnBroadfoot suggests.
