1 1 Preparing Windows 2000 installation (Week 3, Wednesday 2/25/2006) © Abdou Illia, Spring 2006

2 2 Learning Objective Know W2K Server Requirements/Features Understand 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 W2K License Manager  Find objects in Active Directory

3 3 Windows 2000 Requirements Workstation A Workstation B Workstation C Server Windows 2000 Professional Minimum Requirement: - 32 MB of RAM MB of free hard drive space Maximum Hardware specifications: - Support up to 2 processors - Support up to 4 GB of RAM Windows 2000 Server Minimum Requirement: MB of RAM - 2 GB of free hard drive space - NIC Maximum Hardware specifications: - Support up to 4 processors - Support up to 4 GB of RAM

4 4 W2K Server features Supports file, print, application, and Web servers Supports a complete set of services based on Active Directory services Ideal for small- to medium-size enterprise application deployment

5 5 Workgroup vs. Domain Domain:  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.

6 6 Workgroup vs. Domain 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 which contains user accounts, other resources, and security information for that computer  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)

7 7 Win NT vs. Win 2000 domains Win NT  Before the installation, you need to know whether the server will be a DC or a MS.  If you install as a MS, you need to reinstall the OS to make the server a DC. Win 2000:  You install as Stand-Alone or Member Server  After installation, you can decide to make the server a DC or not. Domain Controller Member Server Start Stand-Alone Server Member Server Start Domain Controller Non Domain Controller

8 8 File Systems: FAT vs. NTFS Disks can be formatted using, basically, two types of formatting systems: FAT & NTFS Windows 2000 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? YES (All ver.)

9 9 Licensing modes Client Access Licenses (CAL) needed to access Win 2000 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 2000 Server Win 2000 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

11 11 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 2000 Server and Active Directory services. Configure the remaining computers with Microsoft Windows 2000 Professional. Join each computer to the same domain. b)Configure each computer with Windows 2000 Professional and join them to the same workgroup. c)Configure one of the computers with Windows 2000 Server and Active Directory services. Configure the remaining computers with Windows 2000 Professional. Join each computer to the same workgroup. d)Configure each computer with Windows 2000 Professional and join them to the same domain.

12 12 Summary Questions You are setting up a network for a company that uses about 100 computers. All computers should be on the network. The company requires centralized administration. Each user should be able to use a single logon process to gain access to network resources, such as file, print, and application resources. The company expects to grow steadily and wants to be able to add computers and users as necessary, without having to redesign the network. Which solution should you use? a)Create a parent domain and join all computers running Microsoft Windows 2000 Server to that domain. Create a workgroup and join all computers running Microsoft Windows 2000 Professional to that workgroup. b)Create a workgroup and join all computers to that workgroup. c)Create a parent domain and child domains as necessary and join each computer to the appropriate domain.

13 13 Summary Questions What advantages does a Microsoft Windows 2000 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 2000 Server? a)Client Access License b)Per Server c)Per Connection d)Per Seat

14 14 Summary Questions Your network include two Win 2000 servers and 13 workstations. During W2K 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?

15 15 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)

16 16 Active Directory Individual resources are called objects Objects belong to a Classes Each Class has its own attributes & properties User accountsComputersPrintersDomains Object classes Object name Object unique Identifier Required attributes Optional attributes Parent relationship Username User’s full name Password Account description Remote access OK Username: John Full mane: Johnny Doe Passord: 12#$ms Description: Consultant in Sales depart.
