I would like to remote control the administrator user of my Windows Server 2008 R2 simultaneously from 3 remote computers. To do that, in Group Policy, I disabled "restrict to a single remote desktop session" and I put "limit number of connections" to 3. Then, I restarted the server but it didn't work. When I tried to connect the third remote computer, I got a message saying "select a user to disconnect so that you may login / there are too many users logged in".
I cannot have more than 2 concurrent sessions. I read that I need to buy “CALS” … I read also somewhere that there are already 5 “CALS” with Windows Server 2008 R2… Honestly, I’m lost and I don’t know what to do!
Please help !
Thank you.

No. You can have up to two simultaneous administrative connections to a Windows machine simultaneously, as per your license agreement.
Any more than 2 simultaneous sessions requires a terminal services/remote desktop services installation and client access licenses (CALs).
