Horizon 7 supports at most one desktop session and one application session per user on an RDS host. You must configure the RDS host to restrict users to a single session. For Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2, you can can restrict users to a single session by enabling the group policy setting Restrict Remote Desktop Services users to a single Remote Desktop Services session. This setting is located in the folder Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections. For Windows Server 2008 R2, you can also use the following procedure to restrict users to a single session.
