RDS in Win 2012 server.

Hello,

I am new to RDS and just want to know the exact features needed for a standalone TS.

In the past I have already build one and installed Session host, web access, connection broker,  licensing  and a collection.

Do I really need all those roles or like before, should I simply install session host and licensing for say 10 users.

I dont need any new features like app-v etc, just the simple old style terminal server.

Thanks in Advance
