Remote Web Access Server 2012 R2
Microsoft Remote Desktop Web Access (Microsoft RD Web Access) is a Remote Desktop Services role in Windows Server 2008 R2 and Windows Server 2012 that allows users to access RemoteApp and Desktop Connection through the Start menu or a Web browser.
RD Web Access also includes Remote Desktop Web Connection, which allows users to connect remotely to the desktop of any computer where they have Remote Desktop Access. RD Web Access must be configured to specify the source that provides the virtual desktops and RemoteApp programs that are displayed to users. It can be configured using either RemoteApp source or Remote Desktop Connection Broker (RD Connection Broker) server, which provides users access to virtual desktops hosted on RD Virtualization Host servers and RemoteApp programs hosted on RD Session Host servers.
