If you are using 2X ApplicationServer, you still require Microsoft Terminal Services CALS. Below find links to the Microsoft articles on licensing Windows 2000 http://www.microsoft.com/technet/prodte ... icens.mspx Windows 2003 http://www.microsoft.com/windowsserver2 ... s2003.mspx
With 2X ApplicationServer for Windows Terminal Services companies can reap the benefits of thin client computing without having to switch the network infrastructure to a thin client OS. Rather than deploying particular windows applications onto all your desktops, resulting in an administration and support nightmare, install the application on one central server and use 2X ApplicationServer for Windows Terminal Services to seamlessly publish the application onto remote desktops. Users will never know that the application is running remotely and you will be able to manage the application from a single location! Transmitting just the screen updates rather than the client server data is often faster too.
