SBS Remote Web Workplace are entirely different from Terminal Services. A SBS 2003 R3 can’t be a Terminal Server, thus you need to use RWW if you want to access your server / desktop remotely. Unlike Terminal Services you can more than 2 remote sessions using RWW and again Terminal Service and RWW are two different things an SBS can’t be a Terminal Server, so no confusion.

So if you want to run LOB (line of business) applications on a terminal server then you can add one windows server in a SBS domain as a Terminal server and let the user use the application on that server.

So you got the answer clearly  — cheer up now 🙂
