Operating System

Optimizing Applications for Windows 2000 Terminal Services and Windows NT Server 4.0,


Terminal Server Edition

White Paper

Abstract

Terminal Services is a configurable service incorporated into the Microsoft® Windows® 2000 Server operating system that delivers the Windows 2000 Professional desktop and 32-bit Windows-based applications to diverse desktop platforms. Terminal Services can run any well-behaved Windows-based application, but its multiuser nature tends to expose flaws and shortcuts in applications.

This paper provides guidelines for ensuring that applications run well under Windows 2000 Terminal Services. It also provides information on enhancing the user experience by tuning the application for the Terminal Services environment, and taking advantage of the capabilities Terminal Services provides.
