This Wiki article runs you through the setup of deploying the Standard deployment type of Remote Desktop Services (Session Virtualization) in Windows Server 2012 using the Scenario Based Deployment. The Standard deployment type is used in scenario's where you want to spread the RDS roles over different servers. If you want to run all roles on a single server, follow this Wiki: Deploying the RDS Quick Start deployment type in Windows Server 2012 (for Session Virtualization)

Select the server you want to deploy the RD Connection Broker role on. Note that during this wizard this can only be one server, you can add additional servers later.

And finally choose the server(s) you want to deploy the RD Session Host role on.
