  1. 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 EnvironmentChapter 3:Creating and Managing User Accounts

  2. Objectives • Understand the purpose of user accounts • Understand the user authentication process • Understand and configure local, roaming, and mandatory user profiles • Configure and modify user accounts using different methods • Troubleshoot user account and authentication problems 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  3. Introduction to User Accounts • A user account is an Active Directory object • Represents information that defines a user with access to network (first name, last name, password, etc.) • Required for anyone using resources on network • Assists in administration and security • Must follow organizational standards 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  4. User Account Properties • Primary tool for creating and managing accounts is Active Directory Users and Computers • Active Directory is extensible so additional tabs may be added to property pages • Major account properties that can be set include: • General • Address • Account • Profile • Sessions 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  5. Activity 3-1: Reviewing User Account Properties • Objective is to review properties of user accounts through main tabs of Active Directory Users and Computers • Start  Administrative Tools  Active Directory Users and Computers  Users  AdminXX account  Properties • Explore tabs and values as directed 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  6. The Account Tab of Properties 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  7. User Authentication • The process by which a user’s identity is validated • Used to grant or deny access to network resources • From a client operating system • Name, password, resource required • In Active Directory environment • Domain controller authenticates • In a workgroup • Local SAM database authenticates 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  8. Authentication Methods • Two main processes • Interactive authentication • User account information is supplied at log on • Network authentication • User’s credentials are confirmed for network access 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  9. Interactive Authentication • The process by which a user provides a user name and password for authentication • For domain logon, credentials compared to centralized Active Directory database • For local logon, credentials compared to local SAM database • In domain environments, users normally don’t have local accounts 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  10. Network Authentication • The process by which a network service confirms the identify of a user • For a user who logs on to domain, network authentication is transparent • Credentials from interactive authentication valid for network resources • A user who logs on to local computer will be prompted to log on to network resource separately 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  11. Authentication Protocols • Windows Server 2003 supports two main authentication protocols: • Kerberos version 5 (Kerberos v5) • NT LAN Manager (NTLM) • Kerberos v5 is primary protocol for Active Directory environments but is not supported on all client systems • NTLM is primary protocol for older Microsoft operating systems 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  12. Kerberos v5 • Primary authentication protocol used in Active Directory domain environments • Supported by Windows 2000, Windows XP, Windows Server 2003 • Protocol followed: • Log on request passed to Key Distribution Center (KDC), a Windows Server 2003 domain controller • KDC authenticates user and, if valid, issues a ticket-granting ticket (TGT) to client system 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  13. Kerberos v5 (continued) • When client requests a network resource, it presents the TGT to KDC • KDC issues a service ticket to client • Client presents service ticket to host server for network resource • Every domain controller in Active Directory environment holds role of KDC • Not all clients follow this protocol 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  14. NTLM • A challenge-response protocol • Used with operating systems running Windows NT 4.0 or earlier or with Windows 2000 or Server 2003 when necessary • Protocol followed: • User logs in, client calculates cryptographic hash of password • Client sends user name to domain controller 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  15. NTLM (continued) • Domain controller generates random challenge and sends it to client • Client encrypts challenge with hash of password and sends to domain controller • Domain controller calculates expected value to be returned from client and compares to actual value • After successful authentication, domain controller generates a token for user for network access 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  16. User Profiles • A collection of settings specific to a particular user • Stored locally by default • Do not follow user logging on to different computers • Can create a roaming profile • Does follow user logging on to different computers • Administrator can create a mandatory profile • User cannot alter it 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  17. User Profile Folders and Contents 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  18. Local Profiles • New profiles are created from Default User profile folder • User can change local profile and changes are stored uniquely to that user • Administrator can manage various elements of profile • Change Type • Delete • Copy To 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  19. Activity 3-2: Testing Local Profile Settings • Objective is to configure and test a local user profile • Start  Administrative Tools  Active Directory Users and Computers  Users  New  User • Follow directions to create a new user profile • Explore and configure properties • Test by logging in as new user 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  20. Roaming Profiles • Roaming profiles • Allow a profile to be stored on a central server and follow the user • Provide advantage of a single centralized location (helpful for backup) • Configured from Profiles page of Active Directory Users and Computers • Changing a profile from local to roaming requires care – should copy first 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  21. Activity 3-3: Configuring and Testing a Roaming Profile • Objective: To configure and test a roaming user profile • Create a shared folder, copy a local profile to folder, and configure properties of user account to use roaming folder • Follow directions in book to create, configure, and test the new roaming profile 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  22. Mandatory Profiles • Local and roaming profiles allow users to make permanent changes • Mandatory profiles allow changes only for a single session • Local and roaming profiles can both be configured as mandatory • ntuser.dat  ntuser.man 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

  23. Activity 3-4: Configuring a Mandatory Profile • Objective: To configure and test a mandatory user profile • Start  My Computer • Follow directions to make previously created test profile mandatory by renaming file • Test that no permanent changes can be made by user 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment
