No Machine floating Terminal Services

You can use Terminal Services to bring individual Windows applications to your desktop as floating windows.

SeamlessRDP

To do this you must first install the SeamlessRDP extensions on your Terminal Server. Simply copy the files somewhere. I used c:\bin.

Then you must create a new Custom No Machine session with Floating Window set. The Command to run is:

rdesktop <server> -A -s 'c:\bin\seamlessrdpshell <application>'

Here, server is the Terminal Server and application is the Windows application to run. In the screenshot above I used %COMSPEC% to launch a command prompt. From this you can run other applications as needed.
