A network-based authentication scheme is provided that performs authentication in a centralized manner for the stand-alone computers of a particular organization. Since authentication is centralized, the individual computers do not need to store authentication information, and control over all of the computers rests in a single location, enabling the system administrator to manage access and utilization of the computers from this location. The network-based authentication scheme includes an authentication manager, remotely located with respect to a local computer, that performs authentication for the local computer. The authentication manager receives login information from the local computer, verifies this information against an authentication file, and returns indications of the services on the local computer that the user is able to utilize. The local computer receives these indications and displays icons representing the services available to that user. The user may then select an icon, causing an applet to be downloaded from the authentication manager onto the local computer to facilitate the user's utilization of the corresponding service.
