Connecting to Computers Using Dial-Up Networking

Windows XP Professional can be used within a local network or it can act as a remote client, accessing another computer, a private network or the Internet. There are several options to be considered when creating a connection including:

• Choosing the hardware and network infrastructure for connection

• Defining the authentication that will be used

• Deciding whether data encryption will be used

A dial-up connection has the following characteristics:

• The remote user chooses to use dial-up networking with a standard modem and has access to the Public Switched Telephone Network (PSTN), ie: the ordinary telephone service, also known as Plain Old Telephone Service (POTS).

• The remote user knows the phone number that will be used to access the remote server.

• The remote user can negotiate a common authentication protocol with the server they will access. Eg: with dial-up networking you can use Challenge Handshake Authentication Protocol (CHAP), Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) or MS-CHAPv2.

• The remote user and the server they will access may or may not use data encryption, based on settings configured on the server.

• The remote client requests network protocol information and configuration settings from the server they will access, eg: the server would assign the remote connection a unique IP address, which is then used to access remote network resources, such as file shares.

In the next few pages we will look in more detail at connection options, remote access security, how to setup a modem and instructions for installing and configuring various dial-out connectivity options.

A record of the actions you have taken to connect to computers using dial-up networking can contribute towards your logbook for this unit.
