Terminal Services

1
Terminal Services

• Terminal Services is the modern equivalent of
  mainframe computing, in which servers perform
  most of the processing and clients are relatively
  simple devices that provide the user interface.
• Terminal Services works by running applications
  on a Windows Server 2008 server and enabling
  desktop computers to operate those applications
  from a remote location.

2
Terminal Services Components

• Terminal Server
• Remote Desktop Connection Client
• Remote Desktop Protocol (RDP)

RDC and ActiveX Control

• By default, Windows Server 2008 Terminal Services
  includes the downloadable ActiveX control for
  clients that are not running Remote Desktop
  Connection 6.0 or later.
• This includes all computers running Windows
  operating systems prior to Windows XP SP2, and
  Windows XP SP2 computers that dont have RDC 6.0
  installed.

Planning a Terminal Services Deployment

• Security
• Licensing
• Local resources
• Memory management

Advantages of Terminal Services

• Reduced client hardware requirements.
• Simplified application deployment.
• Easy configuration and updates.
• Low network bandwidth consumption.
• Support for thin clients.
• Conservation of licenses.
• Power savings.
• No client backups.
• Remote control help and training.

Terminal Services

• Keep in mind that while Terminal Services might
  save money on desktop hardware, you might have to
  upgrade your servers (or purchase additional
  ones) to support the Terminal Services traffic,
  and you will certainly have to purchase Terminal
  Services client access licenses (TS CALs) for
  your users or devices.

10
Terminal Services Hardware

• The selection of appropriate hardware for a
  terminal server should be based on the following
  factors
• Number of users connected to the server at any
  one time.
• Applications users need.
• Number of users who access each application.
• Using RemoteApp vs complete remote desktops.

11
RemoteApp

• RemoteApp is a new Terminal Services feature that
  enables clients to run terminal server
  applications within individual windows.
• The windows are resizable.
• They have standard system menu and title bar
  buttons, and they are not constrained by a
  Terminal Services desktop.
• A RemoteApp window is, in most cases,
  indistinguishable from a window containing a
  local application.

12
RemoteApp

• When two different client computers launch
  RemoteApp applications using the same terminal
  server, the server creates two separate sessions,
  each with its own virtualized environment.
• However, when a single client computer launches
  two RemoteApp applications on the same terminal
  server, the server uses one session for both
  applications.
• Therefore, it is possible for a fault in one
  application to affect the performance of the
  other.

13
Terminal Server Licensing

• A Terminal Services deployment needs only one TS
  Licensing server for the entire installation
  regardless of the number of terminal servers on
  your network.
• The process of installing a TS Licensing server
  and preparing it for use consists of the
  following basic steps
• Install the TS Licensing role service.
• Activate the TS Licensing server.
• Install the TS CALs on the TS Licensing server.
• Configure the licensing settings on the terminal
  servers.

Summary

• Terminal Services works by running applications
  on a Windows Server 2008 server and enabling
  desktop computers to operate those applications
  from a remote location.

20
Summary

• To make the desktop or application appear on the
  client computer, the server transmits data and
  instructions that enable the client to render the
  graphical interface on its display.
• In return, to manipulate the applications running
  on the server, the client program transmits the
  users keystrokes and mouse movements.

21
Summary

• Terminal Services implements the server, client,
  and protocol elements with the following three
  components Terminal Server, Remote Desktop
  Connection client, and Remote Desktop Protocol
  (RDP).

22
Summary

• Clients connecting to a Windows Server 2008
  terminal server must have client access licenses,
  in addition to any licenses needed for their
  operating system and applications.
• Terminal Services provides a 120-day grace period
  during which licenses are not necessary.

23
Summary

• RemoteApp is a new Terminal Services feature that
  enables clients to run terminal server
  applications within individual windows. The
  windows are resizable they have standard taskbar
  buttons, and they are not constrained by a
  Terminal Services desktop.

24
Summary

• A virtual server is a complete installation of an
  operating system that runs in a software
  environment emulating a physical computer.
• Applications such as Microsoft Virtual Server
  2005 and the Windows Server virtualization
  technology in Windows Server 2008 make it
  possible for a single computer to host multiple
  virtual machines, each of which runs in a
  completely independent environment.

25
Summary

• Hyper-V is a new server role that provides
  hypervisor-based virtualization on 64-bit Windows
  Server 2008 computers.
• This enables the administrator to create multiple
  virtual machines on a single physical computer,
  each of which runs a separate operating system.
• You can virtualize individual applications, as
  well as operating systems, by using Terminal
  Services RemoteApp or Microsoft SoftGrid
  Application Virtualization.
