Windows XP Professional Authentication Process
To gain access to a computer running Windows XP Professional or to any resource on
that computer (whether the computer is configured to use the Welcome screen or the
Log On To Windows dialog box), you must provide a user name and possibly a pass-
word. (You will learn more about using passwords effectively in Chapter 7.)
The way Windows XP Professional authenticates a user depends on whether the user
is logging on to a domain or logging on locally to a computer (see Figure 1-8).
