1. 1 Preparing Windows 2003 installation (Week 3, Wednesday 1/24/2007) © Abdou Illia, Spring 2007

2. 2 Learning Objective Understand W2003 Installation Requirements Discuss difference between  Workgroup and Domain  FAT and NTFS file systems  Per-Server and Per-Seat licensing modes Do Hands-on  Viewing network computers & shared resources  Using W2003 License Manager  Find objects in Active Directory

3. 3 Windows Server 2003 Requirements Workstation A Workstation B Workstation C Server Windows Server 2003, Enterprise Edition Minimum Requirements: - CPU speed: 133 MHz (x86) minimum - RAM: at lest 128 MB. 256 MB minimum recommended - Disk Space: 1.5 GB of free space - NIC Maximum Hardware specifications: - Support up to 8 processors - Support up to 32 GB of RAM (x86)

4. 4 Win Server 2003, Enterprise Ed. Supports file, print, application, and Web services Supports a complete set of services based on Active Directory services Ideal for small to medium-size enterprise application deployment

5. 5 Domain A domain is:  A logical grouping of servers and other network resources that share a central directory database (Active Directory) Types of computer in a domain:  Domain controllers (DC) running a Server OS  Each domain controller maintains a copy of Active Directory  Each domain controller can authenticate users  Member server (MS) running a Server OS.  A MS is not configured as a DC  A MS doesn't store a copy of AD  A MS cannot authenticate users  Client computers running a Workstation OS Domain administrator has absolute right to set policies within a domain Note: A domain does not refer to a single location. In a domain, computers can share physical proximity on a small LAN or can be located in different corners of the world. DNS Service

6. 6 Workgroup A logical grouping of networked computers that share resources such as files and printers.  Called Peer-to-Peer network because computers can share resources as equals, without a dedicated server.  In a Workgroup, each server and each workstation maintains a local database (called SAM* database) which contains user accounts, other resources, and security information for that computer  Each computer uses local files for address resolution (LMHOST, ARP)  In a Workgroup, the administration of user accounts and resource security is decentralized:  A user must have a user account on each computer the user needs to access  Any change to a user account must be made on each computer  Convenient for small groups (≈ 10 computers)  Servers are referred to as Stand-alone servers because they don’t control access to network resources * Security Accounts Manager LMHOST file ARP table

7. 7 Win Server 2003: Server status Can install as Stand-Alone (P2P) or Member Server (Domain) After installation, you can decide to make the server a Domain Controller or not. Stand-Alone Server Member Server Start Domain Controller Non Domain Controller

8. 8 File Systems: FAT vs. NTFS Disks can be formatted using two types of formatting systems: FAT & NTFS Windows 2003 supports both File Allocation Table (FAT) and NT File System (NTFS) FAT:  Is an older file system designed for computers with small disk storage  Offers less data security than NTFS Long file names (<= 256 characters) File-level and directory-level security Data compression Disk quotas management for disk usage control File encryption Needed for AD services NTFS Features FAT16FAT32NTFS Supported by MS- DOS, Win 3.x and Win 95 OSR1 ? YESNO Supported by Win 95 OSR2 & Win 98? YES NO Supported by Win NT 3.51 & Win NT 4.0? YES YES (NTFS 4.0) Supported by Win 2000 and Win 2003? YES (All ver.)

9. 9 Licensing modes Client Access Licenses (CAL) needed to access Win 2003 servers Two Licensing modes: Per-Server and Per-Seat Per-Server:  CALs are assigned to a particular server  You must have at least as many CALs as the maximum number of workstations used to connect at the same time Per-Seat:  CALs are assigned to workstations  You must have a CAL for each workstation used to connect. Win 2003 Server Win 2003 Server Workstation Per-Server: Need 3+3=6 CALs if 3 concurrent connections Per-Seat: Need 5 CALs to have all Workstation capable to connect all time Best choice if users require frequent access to multiple servers

10. 10 Monitor server hardware using Device Manager The Device Manager displays devices arranged by related category and will, by default, expand any categories that contain devices with problems. Devices with problems are represented superimposing a particular icon on the device label/icon:  “?” indicates a device with no driver for the operating system.  A red “X” indicates a device that has been disabled by the user.  A yellow “ ! ” indicates a device that has been disabled by the operating system.  A yellow “ ? ” covered by a red “X” indicates a device that is either not configured properly or has an incorrect device driver assigned to it. Some hardware devices have an applet in Control Panel that may be used to not only view and but also manage their hardware settings. A device driver is software written for a particular device and specific operating system to allow the OS to interact with the device.

12. 12 Summary Questions You are setting up a network for a small company that uses only five computers. All users and their computers are located in the same office. All computers should be on the network. The company does not require centralized security. Users share files regularly and share the same printer. You need to implement this network for as little expense as possible. Which solution should you use? a)Configure one of the computers with Microsoft Windows Server 2003 and Active Directory services. Configure the remaining computers with Microsoft Windows XP Professional. Join each computer to the same domain. b)Configure each computer with Windows XP Professional and join them to the same workgroup. c)Configure one of the computers with Windows Server 2003 and Active Directory services. Configure the remaining computers with Windows XP Professional. Join each computer to the same workgroup. d)Configure each computer with Windows XP Professional and join them to the same domain.

13. 13 Summary Questions What advantages does a Microsoft Windows Server 2003 domain provide? a)Centralized administration b)Separate user accounts for each computer c)A single logon process Which two licensing modes are supported by Microsoft Windows Server 2003? a)Client Access License b)Per Server c)Per Connection d)Per Seat

14. 14 Summary Questions Your network includes two Win 2003 servers and 13 workstations. During server installation, the Per-Server licensing mode was selected. How many CALs are needed in order for all workstations to connect concurrently to the network? __________________________ You find that the sound card you just installed in your new Windows Server 2003 computer is not generating any sound. You open Device Manager and see the device listed but covered with a yellow “!”. What does this mean? a. The device has no device driver configured. b. The device has an improper device driver configured. c. The device has been disabled by the user. d. The device has been disabled by the system.

15. 15 Summary Questions What does Device Manager do by default to categories containing problematic or non-functional hardware devices? a. It superimposes a red “X” over the category. b. It collapses the category. c. It expands the category. d. It superimposes a yellow “?” over the category. Which of the following devices has its own applet in Control Panel to allow you to interact directly with it and its assigned system resources without having to resort to Device Manager? a. CD-ROM drives b. modems c. floppy disk controllers d. hard disk controllers

16. 16 Summary Questions You open Device Manager and see an expanded category containing a device that has a yellow “?” with a red “X” superimposed on it. What does this mean? a. The device has no driver associated with it. b. The device has a non-functional or improper driver associated with it. c. The device is unknown to the system. d. The device has been uninstalled by the system.

17. 17 Active Directory Central Database that store information about all Network resources Tools for performing central management of users, groups, security services, and network resources (create, find, add, remove, configure etc.) Central Database used for:  Resource lookup (Searching for specific resources)  User authentication (login)
