Lotus Notes Client release 5.0.3 and later R5 releases are considered supported when deployed on Microsoft Windows 2000 Terminal Services (WTS).
Microsoft Windows NT Server, Terminal Server Edition, [version 4.0] gives the Windows NT Server operating system the capability to serve the 32-bit Microsoft Windows operating system-based applications to terminals and terminal emulators running on PC and non-PC desktops. The Terminal Server environment is, by definition, a thin-client architecture where all application processing occurs centrally on the server.
Windows 2000 Terminal Services is a technology that lets you remotely execute applications on a Windows 2000-based server from a wide range of devices over virtually any type of network connection. With the integration of Windows 2000 Terminal Services into the core server operating system, you can choose to deploy the latest Windows-based applications in a fully server-centric mode, where applications run entirely on the server.
