Overview

Introduction

The Install Server Roles module provides you with the instruction and computer hardware to develop your hands on skills in the defined topics. This module includes the following exercises:

  • Installing and Configuring DHCP
  • Installing and Configuring DNS
  • Installing WINS
  • Understanding Network Time Protocol

Exercise 1 - Installing and Configuring DHCP

Dynamic Host Configuration Protocol (DHCP) is a network service that leases out IP addresses to client computers on a network. DHCP streamlines the allocation of IP addresses to computers as it prevents duplicate IP addresses and ensures correct configuration of network settings like subnet mask, default gateway and DNS. Once an IP address is leased to a DHCP client, the DHCP server will not assign that address to another requesting client computer.

Exercise 2 - Installing and Configuring DNS

Domain Name System (DNS) is a network service that translates computer names or hostnames to numeric IP addresses. Although largely associated with the Internet, DNS can be used in a private network for:

  • Simplicity - Computer names are easier to remember and recall than numerical IP addresses.
  • Consistency- IP addresses can change while computer names can remain the same.

In this exercise, you will learn to install and configure DNS.

Exercise 3 - Installing Windows Internet Name Service (WINS)

Windows Internet Name Service or WINS is a legacy name resolver that was used with the earlier Windows operating system versions, such as Windows NT and Windows 9x. WINS helps resolve NetBIOS names to numeric IP addresses and vice-versa. Although supported by the latest Windows versions for backward compatibility, WINS has been largely replaced by DNS for name resolution.

Exercise 4 - Understanding Network Time Protocol (NTP)

Network Time Protocol (NTP) is the time synchronization protocol used by Windows Time Service. The Windows Time Service synchronizes time between computers in an Active Directory domain, with the clock on the domain controller used as reference.

Time synchronization between servers and workstations is vital to the functionality of various network services. Common network services include Active Directory authentication, Exchange messaging services and Certificate Services. For example to ensure a successful authentication with Active Directory, the client computer’s system time must be in sync with the domain controllers’.
