1 Windows XP Users, Groups, Profiles and Policies : MCSE Guide to Microsoft Windows XP Professional

2 Windows XP Professional User Accounts  Designed for use as a network client for: Windows NT Windows 2000 Windows Server 2003  Member of a workgroup  Standalone operating system when more than one user is using the computer Home or business environment

3 Types of Windows XP Professional User Accounts  Local user account Exists on a single computer Can provide access to resources if the user is a member in a workgroup No domain access  Domain user account Created on a domain controller using "Active Directory" and exists throughout the domain Available on any domain member computer

4 User Account Details  Uniquely identified to the system by user account name and password Provides secure access to authorized users  Preferences are environmental settings that are stored in a profile Desktop, Favorites, My Documents, Start Menu, Internet files and Cookies, etc.

5 Accounts Interaction with an XP Professional System (Page 1)  Standalone system, automatic logon— All users access local resources through a "common user account" that automatically logins in when computer starts  Standalone system— Each user logs into system with access to "their own" local resources

6 Accounts Interaction with an XP Professional System (Page 2)  Workgroup member— Users login to an account both local and shared resources  Domain network client— Users login to system with a unique domain user account to gain access to local and domain resources

7 Supporting More Than One User  Multiple-user systems—support more than one user on the same machine, either on a single computer or in a domain  Implemented through: Groups Resources Policies Profiles

8 Groups  Named collections of user accounts One user account may be a member of more than one group  Members of group receive access rights and restrictions for that group  Local groups are created using Windows XP professional and provide privileges at the machine level

9 Resources  Useful objects including printers, shared directories, software applications, etc.  Limited to a single user, group or all users on a machine or within a network

10 Policies  A set of configuration options for a user, computer or group: Define password restrictions, i.e.  Is the user required to change their password at prescribed intervals? Account lockouts, i.e.  What happens if a user enters an incorrect login several times in sequence? User rights Event auditing

11 Profiles  User environmental settings including Desktop, Favorites, My Documents, Start Menu, etc.  A local profile exists on local computer  A domain profile follows a user no matter which computer he/she logons to in the domain

12 Types of Logon  Two types: Windows Welcome Logon Method Classic Logon Method  Changing between the login types is found in "User Accounts" applet in Control Panel  Logon authentication has two purposes: Maintain security Track computer usage

13 Windows Welcome Logon Method (Page 1)  Completely new logon method designed for use on standalone or workgroup member systems  Not available when the Windows XP client is a member of a domain  Displayed as a list of user accounts each with its own icon which the user clicks  For accounts with password, user is prompted for it before access is granted View Windows Welcome Logon Screen

14 Windows Welcome Logon Method (Page 1) Last slide viewed

15 Windows Welcome Logon Method (Page 2)  To turn the Welcome screen on or off: 1. Open User Accounts in Control Panel 2. Click Change the way users log on or off command 3. Do one of the following:  Specify that users log onto computer using the Welcome screen, select the Use the Welcome screen check box  Specify that users log onto computer using "Windows Classic Logon" dialog, clear the Use the Welcome screen check box View Classic Logon DialogView Windows Welcome Logon Screen

16 Windows Welcome Logon Method (Page 3)  Fast User Switching: Allows switching from one user to another without logging off (not in a domain and only for Welcome Screen logon) Also updated in "User Accounts" from Change the way users log on or off From "Start" menu, select the Log Off… command; then in the "Logoff Windows" dialog click the button When switching back, environment and all programs that were active are restored

17 Activity  Turn on Fast User Switching in the "User Accounts" applet  Activate the Guest account and then practice switching between it and your user account

18 Classic Logon Method  Press the + + key combination to access the "WinLogon" security dialog box  Required for domain member systems Selected automatically when a Windows XP system becomes part of a domain  No user switching available Must log off computer to make it available to the next user View Classic Logon Dialog

19 Classic Logon Method Last slide viewed

20 Activity  In the "User Accounts" applet change between the "Windows Welcome" and "Classic" logon methods  Try logging on using each

21 Logging On to Windows XP  When Windows XP Professional first is installed, two accounts are automatically created Administrator Guest

22 Administrator (Page 1)  Most powerful user account possible  Unlimited access and unrestricted privileges to manage users, groups, O/S environment, printers, shares, storage devices, etc.  Must be protected from misuse Complicated password should be used Account should be renamed

23 Administrator (Page 2)  The original Administrator account: Cannot be deleted Cannot be locked out (occurs when user attempts to logon unsuccessfully) Can be disabled (only performed manually by another administrator account) Can have a blank password (not recommended) Can be renamed (recommended) Cannot be removed from Administrators local group

24 Guest (Page 1)  One of the least privileged user accounts  Limited access to resources and computer activities  Account should be renamed  Member of the "Everyone" group  Recommended to leave account disabled since by default all new objects and shares give full control for group "Everyone"

25 Guest (Page 2)  The original Guest account: Cannot be deleted Can be locked out Can be disabled (disabled by default) Can have a blank password (blank by default) Can be renamed (recommended) Can be removed from the Guests local group

26 Naming Conventions (Page 1)  A predetermined process should be used for creating names on either a network or a standalone system A convention is an accepted practice within an organization or even industry-wide Important since networks usually tend to grow very quickly

27 Naming Conventions (Page 2)  Should incorporate a schemes for naming: User accounts Computers Directories Network shares Printers Servers

28 Naming Conventions (Page 3)  Two common conventions: User name employs first and last name, and a code indicating user's department Group name represents the organization of the firm: department, location, project name, and/or combination of the above

29 Naming Conventions (Page 4)  Needs to be: Consistent Easy to use and understand Easy to create new names using the convention (variations are predetermined) Clearly identify the object's type

30 Managing Local User Accounts  Two types of local accounts: Accounts created from scratch locally Local representations of domain/network user accounts  User Accounts applet Used to create local representation (only for a domain client) In a standalone system, applet becomes a task wizard with easy-to-follow tasks

31 User Accounts Applet in a Domain  Users tab Lists active users Add New User wizard to add users  Advanced tab Access to  Password and passport management  Advanced user management  Secure logon settings

81 Last slide viewed

82 Customizing the Logon Process  The Administrator can alter the default logon process by modifying Winlogon, the process that produces the logon dialog, i.e. Deactivating Ctrl+Alt+Delete to start logon Disabling display of the last username Adding a security warning message Disabling the shutdown button Changing the shell Automating logons Automatic account lockout

83 Deactivating + + to Start Logon  Access to Windows Classic logon window usually is initiated by pressing together the keys + +  Forces the XP security logon sequence  However requirement can be disabled  Edit with Local Security Policy dialog in "Administrative Tools" (Security Options): Interactive logon: Do not require Ctrl+Alt+Delete set to "Enabled"

84 Activity  Deactivate + + for Windows Classic logon dialog: Security Settings  Local Policies Security Options  Interactive logon: Do not require CTRL + ALT + DELETE – Enabled

85 Disabling the Default Username (Page 1)  By default the Classic Logon Window displays name of the last user to logon  May not be secure if the workstation often is left unattended  Edit with Local Security Policy dialog in "Administrative Tools" (Security Options): Interactive logon: Do not display last username set to "Enabled"

86 Activity 6-3  Disabling the default username for Windows Classic logon dialog: Security Settings  Local Policies Security Options  Interactive logon: Do not display last username – Enabled

87 Disabling the Default Username (Page 2)  Many security values also can be viewed and even updated directly in the Registry  To view display of last username value in the registry, run the "regedit" command from Start menu  Run

88 Disabling the Default Username (Page 3)  Locate the key at: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows NT\CurrentVersion\Winlogin  Select the DontDisplayLastUserName value and change it: Enabled = "0" Disabled = "1"

89 Adding Security Warning Message (Page 1)  Might be legally obligated to add a warning message for unauthorized usage  Edit with Local Security Policy dialog in "Administrative Tools" (Security Options): Interactive logon: Message text for users attempting to logon–set to any warning message Interactive logon: Message title for users attempting to logon–title bar text

90 Activity 6-4  Adding a security warning caption and message before logon: Security Settings  Local Policies Security Options  Interactive logon: Message text for users attempting to logon – Authorized CS28 users only! Unauthorized access will be punished to the full extent of the law  Interactive logon: Message title for users attempting to logon – Warning!

91 Adding Security Warning Message (Page 2)  To modify the warning title and text in the registry, locate their keys at: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows NT\CurrentVersion\Winlogin  Select the following: LegalNoticeCaption – title bar text LegalNoticeText – the text message

92 Disabling the Shutdown Button (Page 1)  Windows XP logon window includes Shutdown button Eliminates the potential for unwanted system shutdowns  Edit with Local Security Policy dialog in "Administrative Tools" (Security Options): Shutdown: Allow system to be shut down without having to log on set to "Disabled"  Machine still can be physically powered-off

93 Activity  Disable the shutdown button: Security Settings  Local Policies Security Options  Shutdown: Allow system to be shut down without having to log on – Disabled

94 Disabling the Shutdown Button (Page 2)  To disable the shutdown button in the registry, locate the key at: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows NT\CurrentVersion\Winlogin  Select the ShutdownWithoutLogon value and change it: Enabled = "1" Disabled = "0"

95 Automating Logons (Page 1)  Values for username and password can be coded into Registry to automate logons  When enabled, the login dialog is bypassed  Execute "regedit" from Start menu  Run  Locate the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows NT\CurrentVersion\Winlogin

96 Automating Logons (Page 2)  Registry settings: DefaultDomainName – only when logging into a domain DefaultUserName – your logon name DefaultPassword – delete this key if automatic logon is not turned on AutoAdminLogon – value set to "1" to automate login (Keys that do not exist must be created – right-click on parent node and select the command New  String)

97 Activity  Turn on automatic logon: DefaultDomainName – not required (should be your computer name) DefaultUserName – your account name DefaultPassword – create this key if it already does not exist; leave blank if there is no password AutoAdminLogon – 1

98 Automating Logons (Page 3)  Dialog window to control automatic logons: Execute "control userpasswords2 " from Start menu  Run In new window select the account you wish to make the primary logon Unselect "Users must enter a username and password..." checkbox Click and a dialog box will appear asking you to confirm password Click when you are done

99 Files and Settings Transfer Wizard  Move data files and personal desktop settings from another computer to new Windows XP Professional system  Must have some sort of network connection between the two systems  Transfer files from Windows 95, 98, SE, Me, NT, 2000, or XP systems  Transfer process can take considerable time
