In 4.0.x it was possible to have two connections with the same user. I often used this feature together with a co-worker to show some stuff on the server machine. However, currently when a user with the same username connects, the other connection is dropped. Why was this behavior introduced? What is the current version of having two connection to the same physical display simultaneously?
This change was one of the most requested “improvements” and the topmost reason users of the 3 complained about the 4. They argue that if you are connecting to the same desktop you should do by a different user, not hand over your credentials to somebody.
The old behavior can be restored by changing the server configuration. Somebody will post to tell you how to do it. The problem is obviously that the guest user connecting to your machine should not have at all a system account, but for this to work you will have to wait the NoMachine Anywhere service.
