Terminal Services vs. Remote Desktop Connection
Windows 2000 Remote Connectivity:
Windows 2000 uses only one method of remote connectivity – Terminal
Services. Terminal Services is included with Windows 2000 Server and
Advanced Server. There are also client versions available for Windows
95/98, 2000 Professional, and Windows XP.
Terminal Services in Windows 2000 can be configured in two modes –
Remote Administration and Application Server.
èRemote Administration Mode – This mode allows for only two
Simultaneous connections to any given machine. It is designed to allow
Administrators and a small number of users to access the server remotely.
There are no licensing requirements for remote administration mode.
èApplication Server Mode – This mode is intended to be used in an
environment where applications are installed on the server, and those
Applications are then run by a large number of users remotely via Terminal
Services sessions.
Configuring Application Server mode can be quite complex for a
Number of reasons:
èLicenses must be purchased for the Terminal Services server as well
as for all client machines.
èApplications need to be installed in a specific way – Software
installations can only be performed via Add/Remove Programs in
the Control Panel. Attempts to install software in any other way,
such as simply double clicking on an executable file, will result in an
error message.
Terminal Services is added and configured by checking the Terminal Services box
within the Add/Remove Windows Components feature of Add/Remove Programs as
shown in figure:

Windows 2003 Remote Connectivity:
Microsoft has changed remote connectivity significantly in Windows 2003,
Splitting it up into two separate utilities - Terminal Services and Remote
Desktop Connection.
èTerminal Services only functions in the Application Server mode and is
not installed by default. Remote Desktop Connection has replaced the
Remote Administration mode of Terminal Services and is installed by
default.
èThe details and behavior of Terminal Services for Windows 2003 is
the same as Terminal Services Application Server Mode for Windows
2000. Remote Desktop Connection for Windows 2003 behaves the same
way as Terminal Services Remote Administration Mode for Windows
2000.
Even though Remote Desktop Connection is available by default, the
feature still needs to be activated before remote users can connect to the
server. This is achieved by checking the “Enable Remote Desktop on this
computer” box on the Remote tab of My Computer properties, shown in
Figure.
Remote Desktop client is located under Start > Programs > Accessories >
Communications > Remote Desktop Connection. This is the client part of
Remote Desktop, which is used to connect remotely to other servers
