Overview

Deploying Microsoft WindowsNT Server version 4.0, Terminal Server Edition

This service guide provides a process for designing an implementation and deployment of Microsoft® WindowsNT® Server version4.0, Terminal Server Edition (referred to as Terminal Server in this guide).

This guide illustrates steps for deploying Terminal Server in an enterprise environment. It contains information on assembling a project team, assessing the current environment, designing a solution based on need, testing, piloting, and implementing a full deployment. By following the recommendations set forth in this guide, you can provide users with the functionality of WindowsNT and access to applications based on Microsoft® Windows® in a mixed-client environment, including Windows-based terminals, legacy desktops (Windows- and non-Windows-based), and 32-bit Windows-based desktops.

Applying Core MSF Principles

Structurally, the guide offers project plan guidance based on the core principles of Microsoft Solutions Framework (MSF) and built around the four MSF milestones—Vision/Scope Approved, Project Plan Approved, Scope Complete/First Use, and Release.

Getting To Know Terminal Server

Introducing Microsoft WindowsNT Server 4.0, Terminal Server Edition

Microsoft WindowsNT Server 4.0, Terminal Server Edition is an extension of the WindowsNT product line that provides support for remote access by using thin client software that runs on a new class of Windows-based terminals and on desktop systems running under 16-bit and 32-bit Windows. Terminal Server allows users to run both the Windows desktop operating system and Windows-based applications directly off the server, extending the scalable Windows family and providing users of low-cost terminal devices and legacy hardware with access to the latest WindowsNT–based technology and the latest Windows-based applications.

Terminal Server has three parts. The server itself is a new edition of Microsoft WindowsNT Server 4.0 with the ability to host multiple, simultaneous client sessions. Remote Desktop Protocol (RDP) is the protocol that allows a super-thin client to communicate with Terminal Server over a network. Terminal Server Client is a super-thin client application that connects to Terminal Server from a Windows-based terminal, Microsoft Windows for Workgroups 3.11, Microsoft Windows95 or Windows98, or WindowsNT.

Terminal Server includes Microsoft® Internet Explorer version 4.01 for Web and file system browsing. Active Desktop is not supported in the current release of Terminal Server.

Consult the Start Here and Administration Guide documentation that comes with the Terminal Server software for complete instructions on installing and administering Terminal Server. You can find electronic copies of these documents on the Terminal Server installation CDROM at \support\books.

Determining Business Drivers

Customers who have made the decision to implement Terminal Server typically explain their decision in terms of business drivers. Although not all customers focus on the same set of drivers or give them all the same degree of consideration, a well-implemented Terminal Server deployment will often confer benefits upon the user that exceed those planned for during the initial decision-making process.

Typical business drivers for Terminal Server include administration and network usage, legacy client device replacement, cross-platform compatibility, and Year2000 issues.

Administration and Network Usage

Terminal Server can improve and simplify administration while also optimizing performance over the network.

  • Terminal Server centralizes administration of network resources by putting all applications on servers rather than distributing them to individual desktop computers. This is particularly useful with bandwidth-intensive applications like flat-file systems (for example, Microsoft® FoxPro®). Terminal Server clients can efficiently gain access to an application running on Terminal Server and a fast network segment because of the architecture’s efficient use of bandwidth. All application processing takes place on the server, with only video, mouse, and keyboard traffic passing between the client and Terminal Server.
  • Deploying applications centrally on Terminal Server allows users simultaneous access to upgraded applications. Administrators can deploy custom applications that require frequent incremental upgrades on servers running Terminal Server, significantly reducing time and labor to update the applications for all users.
  • Users can store sensitive data in a central data facility (glass house) rather than on their individual personal computers, substantially decreasing the risk of data loss from theft, natural disasters, and other causes.
  • Remote users can gain access to the same data and applications as local users over dialup or permanent Internet connections and benefit from how Terminal Server efficiently uses bandwidth.

Legacy Client Device Replacement

Terminal Server simplifies the process of replacing legacy hardware and software. If the organization currently uses text-based terminals, it can deploy Terminal Server with a new low-cost, thin client device known as a Windows-based terminal to provide an upgrade path to Windows-based applications.

An organization can also easily install Terminal Server client software on older personal computers used for task-based applications such as terminal emulation or fixed function applications. In this way, end users can obtain access to the 32-bit Windows-based user interface found on Windows95 and98 or WindowsNT 4.0 and to the latest Windows-based applications before they receive new computers.

  • Companies with high employee turnover or seasonal or temporary workers can decrease training costs with Terminal Server because they can replace legacy text-based applications using unfamiliar and non-intuitive user interfaces with newer applications using the familiar Window-based user interface.
  • Many older business applications and development tools are no longer supported by the companies that released them, cannot be upgraded easily, and are often unfamiliar to today’s technical support staff. Terminal Server provides an efficient way to replace these obsolete programs and tools with off-the-shelf Windows-based applications and tools.
  • Terminal Server provides a smooth migration path because users with legacy software or hardware can gain access to new applications through the Terminal Server interface. For example, as an organization upgrades from Office version4.3 to Office 97, users can run older versions of Windows while taking advantage of the latest version of the application prior to a system refresh.
Cross-Platform Compatibility

Users of non-Windows–based computing platforms such as Apple® Macintosh®, UNIX, and Microsoft® MSDOS® can gain access to Terminal Server by using vendor add-on client/server software such as MetaFrame from Citrix Systems. By doing so, an organization can deploy one set of applications and one user interface across all client devices.

  • Organizations can lower training and administrative costs by training users on applications and interfaces together, regardless of platform. In addition, administrators can use Terminal Server to centrally manage applications and system configurations for users of all platforms.
  • By using Terminal Server, a company with mixed desktop environments can deploy common email clients, productivity suites, or other applications to every user while users continue to operate under their individual platforms for job-specific tasks. Thus, the company benefits from the wide range of Windows-based applications without having to replace all desktops.

See Planning Client Deployment in the “Project Plan Approved Milestone” section for more information on using vendor client software with Terminal Server.
