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

Windows Server 2003 Requirements

Workstation A

Workstation B Workstation CServer

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- NICMaximum Hardware specifications:- Support up to 8 processors- Support up to 32 GB of RAM (x86)

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

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

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

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.

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 FAT16 FAT32 NTFS

Supported by MS-DOS, Win 3.x and Win 95 OSR1 ?

YES NO NO

Supported by Win 95 OSR2 & Win 98? YES YES NO

Supported by Win NT 3.51 & Win NT 4.0?

YES YES YES (NTFS

4.0)

Supported by Win 2000 and Win 2003?

YES YES

YES

(All ver.)

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 Workstation Workstation Workstation 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

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.

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

Summary Questions What advantages does a Microsoft

Windows Server 2003 domain provide? a) Centralized administrationb) Separate user accounts for each computerc) A single logon process

Which two licensing modes are supported by Microsoft Windows Server 2003?

a) Client Access Licenseb) Per Serverc) Per Connectiond) Per Seat

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

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 drivesb. modemsc. floppy disk controllersd. hard disk controllers

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.

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.)
