Maximum connections in remote desktop for Windows Server 2008 R2

view story

http://serverfault.com – I am trying to set up my server so that more than 2 people can use it at once. I am looking at the RDP-Tcp Properties window in Remote desktop session host configuration, and it won't get higher than a 2. I have read that I need some sort of licensing, but then it looks like it also include a lot more reconfiguration and turning the server into something else. But I just want to increase the maximum connections to beyond 2, like 5 or 6. What are my options? (HowTos)
