Components.

Telnet
Dial-up Remote access
Terminal Services are included in the Windows Server 2003 as remote access tevhnologies.

Telnet.

Windows 2003 and XP uses the telnet clients and telnet server components, which allows the users to establish the connection remotely based on the telnet protocol.Telnet allows you to create a remote console session on the host. We can run command line programs, shell programs,shell commands and scripts in a remote console session, using local command prompt, as you are locally logged on.

Telnet Client and Telnet Server are suited for admistrating the remote clients especially in mixed environments. That simply means the different environments can connect to each other as clients and server through Telnet. Using telnet offers you an advantage for minimal bandwidth and memory and processor resource are not enough
This is because Telnet Clients and Telnet Server use less memory and processor time than other remote management tools, and Telnet clients and servers transmit only plaintext (unencrypted characters) across the network.

Dial-Up Remote Access:

This is the technology that is available as apart of the Remote Access Services in the Microsoft Windows server 2003. Using the telecommunication infrastructure a dial-up client creates a temporary physical circuit(Virtual circuit) to a port on the Remote Access Server. If the connection is established i.e if the server accepts the dial-up connection from the client, the server forwards data packets between client and the network to which the server is attached.

The connection established between the remote access server(physical or logical) and the remote access client is created using dial-up equipment.Depending on the type of connection used,  The dial-up equipment and network infrastructure can vary.
