XP Professional authenticates the user’s identity during the logon process. Only valid
users can access resources and data on a computer or a network. Windows XP Professional
authenticates users who log on locally to the computer at which they are seated;
a domain controller authenticates users who log on to a domain.

When a user starts a computer running Windows XP Professional that is configured to
use the Log On To Windows dialog box, an Options button also appears. Table 1-1

of a domain.
