12. Chapter 3: Supporting Local Users and Groups12 GROUP ACCOUNTS  Group accounts are used to simplify the assignment of security features by associating user accounts that have common needs.  For example the administrators group will store all users who have administrative rights on the local machine.  Group accounts are used to simplify the assignment of security features by associating user accounts that have common needs.  For example the administrators group will store all users who have administrative rights on the local machine.

13. Chapter 3: Supporting Local Users and Groups13 DEFAULT GROUP ACCOUNTS  There are several default, built-in groups in Windows XP Professional Edition. The most common of these are:  Administrators group  Backup Operators group  Guest group  Power Users group  Users group  There are several default, built-in groups in Windows XP Professional Edition.

15. Chapter 3: Supporting Local Users and Groups15 SECURITY IDENTIFIERS (SIDS)  User accounts and groups are considered security principals. Meaning that you can grant them access on a computer. Every security principal has a unique Security Identifier (SID) assigned to it at the time of creation.  Basically a number associated with a user or a group used for tracking security settings. It is easier for the OS to track a number rather than a Name.  User accounts and groups are considered security principals. Meaning that you can grant them access on a computer.

16. Chapter 3: Supporting Local Users and Groups16 LIMITATIONS OF WINDOWS XP HOME EDITION  Cannot create local groups  Local Users And Groups tool is not available—must use User Accounts tool  Supports only two types of accounts:  Computer Administrator  Limited  Does not have an account named Administrator  Cannot join a domain  Cannot create local groups  Local Users And Groups tool is not available—must use User Accounts tool  Supports only two types of accounts:  Computer Administrator  Limited  Does not have an account named Administrator  Cannot join a domain

17. Chapter 3: Supporting Local Users and Groups17 USER PROFILES  User profiles store user-specific configuration settings, such as customized desktops and personalized application settings

18. Chapter 3: Supporting Local Users and Groups18 Types of profiles Windows XP supports  Local – available only on the PC it was created on. XP pro and Home support this  Roaming – stored in a shared folder on a network server and are accessible from any location in a network. Only XP Pro.  Mandatory – roaming profiles that users cannot make permanent changes to. Mandatory profiles are used to enforce configuration settings. Only XP Pro.  Local – available only on the PC it was created on. XP pro and Home support this  Roaming – stored in a shared folder on a network server and are accessible from any location in a network.

19. Chapter 3: Supporting Local Users and Groups19 DOCUMENTS AND SETTINGS FOLDER – Storage Location for Local Profiles  Windows stores local user profiles in the Documents And Settings folder. This folder stores several files and folders containing configuration information and data for each user profile.

20. Chapter 3: Supporting Local Users and Groups20 LOCAL USER PROFILES  A local user profile is available only from the system on which it was created  A unique local user profile is created and stored on each computer a user logs on to  A local user profile is available only from the system on which it was created  A unique local user profile is created and stored on each computer a user logs on to

21. Chapter 3: Supporting Local Users and Groups21 HANDLING MULTIPLE PROFILES FOR THE SAME USER NAME  If a Windows XP Professional Edition computer is a member of a Windows domain, two users with the same user account name can log on to the same system.  If there were 2 Matts that logged onto a local machine 2 separate folders would be created. 1. C:\documents and settings\matt 2. C:\documents and settings\matt. where is the name of the local PC  If a Windows XP Professional Edition computer is a member of a Windows domain, two users with the same user account name can log on to the same system.  If there were 2 Matts that logged onto a local machine 2 separate folders would be created. 1. C:\documents and settings\matt 2. C:\documents and settings\matt. where is the name of the local PC

22. Chapter 3: Supporting Local Users and Groups22 ROAMING USER PROFILES – stored on a network server - this helps avoid the following 2 problems  Users will have a different profile on each machine they log on to  Without regular backup, if the local machine crashes, the profile could be lost  Users will have a different profile on each machine they log on to  Without regular backup, if the local machine crashes, the profile could be lost

23. Chapter 3: Supporting Local Users and Groups23 ENABLING ROAMING PROFILES  Create and share a folder on the server that will hold the roaming profiles  Make sure that the users have access to the shared folder  Specify the location of the roaming profile folder  Create and share a folder on the server that will hold the roaming profiles  Make sure that the users have access to the shared folder  Specify the location of the roaming profile folder

24. Chapter 3: Supporting Local Users and Groups24 ADDITIONAL POINTS ON ROAMING PROFILES  Roaming profiles are generally used in a domain environment  In a domain account, a roaming profile is created and configured once on a domain controller  Roaming profiles are generally used in a domain environment  In a domain account, a roaming profile is created and configured once on a domain controller

25. Chapter 3: Supporting Local Users and Groups25 MANDATORY USER PROFILES  Mandatory user profiles are applied to roaming user profiles. When a profile is made mandatory, users are unable to save changes to desktop settings.  Used when you don’t want users to change settings, such as desktop backgrounds and icons.  Mandatory user profiles are applied to roaming user profiles.

26. Chapter 3: Supporting Local Users and Groups26 FAST USER SWITCHING  Allows multiple local user accounts to log on to a computer simultaneously  Users can switch sessions without logging off or closing programs  Running programs still consume computer resources  This can really slow down the PC. I would not recommend using it.  Allows multiple local user accounts to log on to a computer simultaneously  Users can switch sessions without logging off or closing programs  Running programs still consume computer resources  This can really slow down the PC.
