2 Implementing Windows Terminal Server and Citrix MetaFrame on IBM ^ xSeries Servers
1.1 Windows Terminal Server
Windows Terminal Server, a component of Windows Server 2003 and Windows 2000 Server,
is designed to distribute Windows applications by using
thin-client technology. A thin client is
a device that is easy to install and connects to a high-powered server running WTS that
provides the computing services the thin client needs. We call the server running WTS the
terminal server. WTS communicates with a small client program installed on any PC or
handheld device.
The user starts the client program, which then displays the name of the terminal server. When
the user double-clicks the terminal server name, the user sees the server’s logon display, as
shown in the example in Figure 1-1. Each user can log on to the terminal server. Then the
remote server provides a Windows XP desktop in the client window. Users can interact with
this desktop just as if they have their own high-powered Windows XP workstation. However,
the processing is performed on the server, not the workstation, which merely provides input
from the user and output to the display.
Figure 1-1 Windows Terminal Server and client relationship
Windows Server 2003 has two Terminal Server modes:
򐂰 Remote Desktop: This allows administrators to remotely log on to the server from remote
workstations. They can enable the Remote Desktop through the system control panel’s
Remote page, rather than installing Terminal Services for Remote Administration in
Windows 2000 Server. Remote Desktop allows remote administration for a maximum of
two concurrent connections. The administrator also has the ability to connect to the server
console by running the Remote Desktop Connection client (mstsc.exe) with the
/console
switch.
Tip: Windows Terminal Server is often also called Windows Terminal Services. These
terms are largely interchangeable.
Terminal Services is the name of a family of related technologies, including Remote
Desktop Connection (RDC), Remote Desktop Protocol (RDP), Terminal Server, Remote
Assistance, and Remote Desktop for Administration.
Terminal Server is the name of the
Windows Server 2003 component that enables multi-user access to applications running
on Windows Server. It is the name that is applied to the Client Access Licenses.
We use the term
terminal server (all lower case) to indicate the server on which Windows
Terminal Server is running.
