Maintaining User Profiles
A profile is an environment specifically customized for a user. The profile contains the desktop and program settings for the user. Every user has a profile, whether the administrator configures one or not, because a default profile is automatically created for each user who logs on to a computer. Profiles offer a number of advantages:
Multiple users can use the same computer, with the settings for each user restored at logon time to the same state as when he or she logged off.
Desktop changes made by one user do not affect any other user.
If user profiles are stored on a server, they can follow users to any computer on the network running Windows Server 2003, Windows XP Professional, Windows 2000, or Windows NT 4.
