Lesson
INSTALL AND CONFIGURE DOMAIN NAME SYSTEM (DNS)
INSTALLATION
CONFIGURING DNS
After installing DNS, you have to go Start —> All Programs —> Administrative
Tools —> DNS for managing DNS server.
Whenever configuring your DNS server, you must be know about following
concepts:
Forward lookup zone
Reverse lookup zone
Zone types
A forward lookup zone is helps to resolve host names to IP addresses. A reverse lookup
zone allows a DNS server to discover the DNS name of the host. Basically, it is the exact
opposite of a forward lookup zone. A reverse lookup zone is not required, but it is easy to
configure and will allow for your Windows Server 2008 Server to have full DNS functionality.
2
When selecting a DNS zone type, you have the following options: Active Directory (AD)
Integrated, Standard Primary, and Standard Secondary. AD Integrated stores the database
information in AD and allows for secure updates to the database file. This option will appear
only if AD is configured. If it is configured and you select this option, AD will store and replicate
your zone files.
A Standard Primary zone stores the database in a text file. This text file can be
shared with other DNS servers that store their information in a text file. Finally, a Standard
Secondary zone simply creates a copy of the existing database from another DNS server.
This is primarily used for load balancing.
Step 6: Click Next on the Zone File Name.

Step 7: Select the Allow both nonsecure and Secure dynamic updates and click Next to
Continue.
Step 8: Select Yes, I want to create reverse lookup zone now, Click Next to
continue.
Step 10: Select Primary Zone in Zone creating Window.
Step 13: Click Next on the Reverse lookup Zone file name window.
Step 14: Select the Allow both nonsecure and Secure dynamic updates and click
Next to Continue.
Managing DNS Server:
After the installation and configuration of the forward and reverse lookup zone, now
the server is ready to create the other records associated with the DNS and Zones.
There are several records available, here is the listing of some of the important
records.
 Start of Authority (SOA)
 Name Servers
 Host (A)
 Pointer (PTR)
 Canonical Name (CNAME) or Alias
 Mail Exchange (MX)

DOMAIN NAME SYSTEM (DNS) INSTALLATION AND CONFIGURATION
Windows administrators use DNS server to the Domain Name System (DNS)
in a hierarchical distributed naming system for computers, services, or any
resource connected to the Internet or a private network. It associates various of information with
domain names assigned to each of the participating entities. Most importantly, it translates
domain names meaningful to humans into the numerical identifiers associated with
networking equipment for the purpose of locating and addressing these devices worldwide.
Before using, we need to install the DNS server and configuring the following
concepts:
 Forward lookup zone
 Reverse lookup zone
 Zone types
