Configuring Domain Name System for Active Directory

Introduction

The Configuring Domain Name System for Active Directory module provides you with the instruction and server hardware to develop your hands on skills in the defined topics. This module includes the following exercises:

• Installing DNS
• Configuring DNS Zones
• DNS Server Settings
• Zone Transfers and Replication

Exercise 1 - Installing DNS

Doman Name System (DNS) is a network service that translates computer names or hostnames to numeric IP addresses or vice-versa. Although largely associated with the Internet, DNS can be used in a private network for the following benefits: Simplicity - computer names are easier to find than numeric IP addresses. Convenience- IP addresses can change but computer names can remain constant.

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

Exercise 2 - Configuring DNS Zones

For an organization that must maintain a presence in the global Internet a publicly registered name is a requirement. This name is normally registered with numerous domain registrars that you can search on the Internet. When a domain name is registered for an organization, it must have a DNS zone created in a public DNS server.

A DNS zone is usually named after the company. When a DNS zone is created, it must contain resource records (RRs) of devices whose names and IP addresses are resolvable either on a local intranet or the public Internet.

In this exercise you will perform the tasks required to create and manage DNS zones.

Exercise 3 - DNS Server Settings

In this exercise you will perform the tasks required configure the DNS server settings.

Exercise 4 - Zone Transfers and Replication

In this exercise you will perform the tasks required to configure zone transfers and replication.
