That’s correct. The Workstation and all the Terminal Server versions work as terminal servers, by creating sessions running in the background. These are terminal servers, intended for the enterprise market. The free 3 worked as a terminal server limited to 2 users. This functionality (virtual desktop) is no longer available in the free version. SSH support which was previously available in the free 3 is now available in the enterprise market-oriented products. If you want to replace NX Free Edition with version 4, the Workstation is what you need.
