The Microsoft Remote Desktop Session Host (RD Session Host) holds the actual user sessions running the published Remote App or Full Desktop.

RDP traffic running on port 3389 must be load balanced in the LoadMaster. In this scenario, the RD Connection Broker role functionality to redirect to an existing (disconnected) session is still in place, but the RD Connection Broker itself does not actively load balance sessions across RD Session Host servers.

After the RD Session Host role is installed, you can use the Remote Desktop Management Services (RDMS) console as part of the Server Manager to retrieve the RD Session Host servers as part of the deployment.

Note: Note that when load balancing the Session Hosts and using the Connection Broker, you must disable Connection Broker load balancing using Group Policy. You can view the required steps in the Implementing Remote Desktop Session Host Load Balancing section.
