1-23Lesson 4 Logging On and Off Windows XP Professional
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 Profes-
sional 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.
