This article describes the Remote Desktop Connection (RDC) client requirements to use Terminal Services Web Access in Windows Server.
Applies to: Windows Server 2012 R2
Original KB number: 943887
Terminal Services (TSWeb) in Windows Server 2008 and Remote Desktop Services (RDWeb) in Windows 2008 R2 are role-based services. They let users start RemoteApp and Desktop Connection from a web browser. RemoteApp and Desktop Connection provides a customized view of RemoteApp programs and virtual desktops to users. When a user starts a RemoteApp program, a Terminal Services session is started on the Windows Server 2008-based terminal server that hosts the RemoteApp program.
To start a RemoteApp program, a user connects to a website that is hosted on the Windows Server 2008-based TS Web Access server. When the user connects to the website, a list of available RemoteApp programs appears. Additionally, TS Web Access lets users connect to the remote desktop of any server or client computer on which the user has the required permissions.
If you're using Windows Server 2008 R2, you must use RDC client version 7.
You must have the RDC client version 6.1 installed to use TS Web Access with the following operating systems:
Windows Server 2008
Windows Vista with Service Pack 1 (SP1)
Windows XP with Service Pack 3 (SP3)
RDC 6.1 (6.0.6001) supports Remote Desktop Protocol 6.1.
If you're experiencing this issue on a Windows Vista-based computer, you must have Windows Vista Service Pack 1 installed on your computer.
If you're experiencing this issue on a Windows XP-based computer, you must have Windows XP Service Pack 3 or RDC 6.1 installed on your computer.
