Each machine on a computer network is assigned a
unique network address. Computers communicate with one another
across networks by connecting to these network addresses. These
numbers, also known as Internet Protocol (IP) addresses, consist of
four groups of
numbers
, or octets, and can be difficult for people
to remember. To solve this dilemma, a system was developed whereby
people can use "friendly" names that are then translated
automatically into IP addresses that computers use to locate each
other and to communicate. These friendly
names
are called
hostnames
, and each machine is
assigned one. Groups of these
hosts
form a
domain
. The software that
translates
these
names to network addresses is called the
Domain Name System (DNS)
.
Before the
advent
of DNS, HOSTS files were used
for name resolution, but as the Internet quickly grew in
size
and
popularity, HOSTS files became
impossible
to maintain and keep
current. When the Internet community realized there was a need for
a more manageable, scalable, and efficient name-resolution system,
DNS was created. Since that time, DNS servers have been used on the
Internet almost exclusively.
Before the introduction of Windows 2000, Network
Basic Input/Output System (NetBIOS) names were used to identify
computers, services, and other resources on Windows-based machines.
In the early days of Windows networks, LMHOSTS files were used for
NetBIOS name resolution. Later, these names were often resolved to
IP addresses using a NetBIOS Name Server (NBNS). Microsoft's
version of the NBNS was called Windows Internet Naming Service
(WINS). With Windows 2000 and Windows Server 2003, hostnames are
used instead of NetBIOS names. In a Windows Server 2003 domain, DNS
is used to resolve hostnames and locate resources such as network
services.
This chapter introduces the Windows Server 2003
implementation of WINS and DNS. You'll learn how to install and
configure both name resolution services, as well as how to maintain
and monitor them. Having a thorough understanding of the topics
presented here is important to both the exam and on-the-job
success.
