We assume that you have a server running Window Server 2012 (Windows Server 8 Beta) that is part of an Active Directory Domain.
Open up the Server Manager Console and choose option 2, “Add roles and features”:
Choose next to start the deployment
Select the “Remote Desktop Services scenario-based installation”
As we want all the roles to be running on the same server, we choose the Quick Start option.
As we are going to be deploying sessions, not Virtual Desktops, we choose Session Virtualization.
We select the server where we want to install the roles
We confirm that we allow the deployment to reboot the server (needed for the RDSH role)
That's it!
The Scenario Based Deployment will now install the RD Session Host, RD Connection Broker and RD WebAccess role, create a first Session Collection and add computers to the Active Directory Groups as needed.
To make the lab even more complete, several applications are already added to the Remote App sections and published on RD WebAccess to give you an environment that can be used for demos instantly!
