User profile settings?
On a computer running Windows 2000, a user profile automatically creates and maintains desktop settings for each user's work environment on the local computer. When a user logs on to a computer for the first time, the system creates a user profile for each user. User profiles provide a variety of conveniences for users: §Multiple users can use the same computer, and each user receives his or her own desktop settings when logging on. §When a user logs on to a workstation, he or she receives the desktop settings from the last time he or she logged off. §A user's customized settings for the desktop environment do not affect the settings of other users. §User profiles can be stored on a server so that they can follow a user to any computer on the network running Windows NT 4.0 or Windows 2000. This is called a roaming user profile. User profiles provide the following options for system administration: ?§Default user profiles can be created that are appropriate for the user's task. ?§Forced user profiles that do not save changes made by the user to desktop settings can be created. A user can modify the computer's desktop settings after logging on, but no changes are saved when the user logs off. The forced user profile settings are downloaded to the local computer each time the user logs on. § You can specify default user settings to be added to all individual user profiles. Each user profile begins with a copy of the default user, which is the default user profile saved on each computer running Windows 2000. The Ntuser.dat file in the default user shows the configuration settings in the Windows 2000 registry. Each user profile also uses the common program groups contained in the All Users folder. Although the settings in the All Users folder are not copied to the User Configuration folder, they can be used to create personal user profiles.Windows2000 supports two types of program groups: the first type of common program group is always available on the computer, regardless of who is logged on. The second type of personal program group is for the exclusive use of the user who created them.
