RDC client requirements for Terminal Services Web Access in Windows Server 2008 and Windows Server 2008 R2

INTRODUCTION
Terminal Services (TSWeb) in Windows Server 2008 and Remote Desktop Services (RDWeb) in Windows 2008 R2 are role-based services that lets 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.

Resolution
If you are using Windows Server 2008 R2, you must use Remote Desktop Connection (RDC) client version 7.

You must have the Remote Desktop Connection (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)
Note RDC 6.1 (6.0.6001) supports Remote Desktop Protocol 6.1.
