In order for you to use any service provided by the server computer it is required that you register yourself inside the server computer creating a user profile. The user profile provides the user information required by services inside the server computer (e.g., username, password, e-mail address, telephone number, etc.). To register new user profiles, you need to use the web application provided by the server computer.

To reach the web interface, the first thing you need to do is establishing a dial-up connection to the server computer as described in . Once the dial-up connection has been established, you need to open a web browser (e.g., Firefox) and put the URL mentioned above in the address space, and press Enter to go. This will present you a web page with the instructions you need to follow in order to register your user profile. Other actions like updating or deleting your own user profile should be also possible from this web interface. The web interface used to manage user profiles inside the server computer must be presented over an encrypted session in order to protect all the information passing through.

The web application provided by the server computer manages all these subsystems' configuration files in order to provide a pleasant experience for end users. The web interface must be as simple as possible in order to achieve all administration tasks in the range of time permitted by the server computer before it closes the connection established from the client computer.
