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

2. 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment 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

3. 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

4. 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

5. 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

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

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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

13. 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

14. 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

15. 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

16. 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

20. 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

21. 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

22. 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

23. 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
