5. Introducing Workgroup and Domains
(Skill 4)
Introducing Workgroup and Domains
Windows Server 2003 operating system supports workgroups and domains, the two basic network model types that enable users to share common resources
A workgroup or peer-to-peer network is a logical group of computers that are interconnected, generally over a local area network (LAN)
A domain is a logical grouping of network computers that share a central directory database

6. Introducing Workgroup and Domains (2)
(Skill 4)
Introducing Workgroup and Domains (2)
Workgroup features
The administration of user accounts and resource security in a workgroup is decentralized
To gain access to resources on any computer in the workgroup, user must have an account on that computer
Workgroup limitations
A workgroup model is practical only in smaller environments where computers are in close proximity
Microsoft recommends that a workgroup consist of less than 10 computers

Manages security-related aspects of user/domain interactions

9. Introducing Workgroup and Domains (4)
(Skill 4)
Introducing Workgroup and Domains (4)
Domain advantages
Centralized security and administration means that a change to any object within the domain is available to the entire domain
Provide a single logon process for users to gain access to network resources, such as file, print, and application resources

DHCP servers manage the dynamic allocation of IP addresses and the related configuration details for DHCP-enabled clients on your network
Domain Name System (DNS)
Main name resolution service for Windows Server 2003
Enables access to computers on a TCP/IP network using the domain name

13. Introducing Network Services in Windows Server 2003 (3)
(Skill 5)
Introducing Network Services in Windows Server 2003 (3)
Windows Internet Name Service (WINS)
Assigns or maps an IP address to a computer name so network users can find a computer on a TCP/IP network using the NetBIOS name
WINS server database provides a lookup directory
Virtual Private Networks (VPNs)
Provide connections to private networks, such as a LAN, through a non-secure communication channel like the Internet
Use tunneling and encryption to create a virtual tunnel for secure information exchange

14. Introducing Network Services in Windows Server 2003 (4)
(Skill 5)
Introducing Network Services in Windows Server 2003 (4)
Routing and Remote Access Service (RRAS)
Allows remote or mobile workers to connect to a firm’s networks so that they can work as if their computers were physically connected to the network
Workers connect to the LAN via modem or Virtual Private Network (VPN)
IAS RADIUS and Load Balancing
Internet Authentication Service (IAS) is Windows Server 2003’s Remote Authentication Dial-In User Service (RADIUS) server component
Network Load Balancing (NLB) allows certain types of servers (mostly file/print servers and Web servers) to scale to a much larger size than would otherwise be possible

15. Introducing Network Services in Windows Server 2003 (5)
(Skill 5)
Introducing Network Services in Windows Server 2003 (5)
IAS Enhancements
Centralize services for wireless users and logs information to a Microsoft SQL server
Allow advanced SQL queries
Provides new 801.1X authentication features and cross-forest authentication
Internet Connection Firewall (ICF)
Supplies basic protection on computers directly connected to the Internet or on LAN segments
Designed for use in a small business
