provide visitors with an easy-to-remember address, such as www.microsoft.com. Name
resolution involves supplying the correct numerical address from the friendly name that was
typed into a client browser.
Name Resolution Systems
Windows networking components rely on the NetBIOS naming convention. In contrast,
TCP/IP components rely on a naming convention known as the Domain Name System
(DNS). Under Windows, the DNS host name of your server appliance defaults to the same
name as the NetBIOS computer name. The mapping of computer names to IP addresses
can be accomplished using one of the following two methods:
Static: The system administrator creates either a text file for DNS names, called a
n
HOSTS file, or an LMHOSTS file for NetBIOS names, and enters each computer's
name and IP address. The file is then distributed on the network. When a request for a
connection to another computer is made, the file is used to resolve the name to the
correct IP address. This system works well for simple networks that change
infrequently.
Dynamic: When a client computer connects to a network with a DHCP server, the
n
DHCP server assigns an address and sends the IP address assignment to a Windows
Internet Name Service (WINS) server. The WINS server registers the computer's
name, and when a request is made for a NetBIOS computer name, the WINS server
resolves the name to the correct IP address. This automatic recognition and mapping of
computer names and addresses eases the administrative burden of large or frequently
changing networks.
DNS names are typically resolved using static information. The DNS server contains a
portion of the static database listing host names and addresses. If the requested name is not
in the DNS server's portion of the database, it sends a query to other DNS servers to get the
requested information. The DNS server that runs on Windows can be configured to query
a WINS server for name resolution of the lower levels of the DNS hierarchical naming
structure. Because WINS assigns computer names dynamically, this effectively changes
DNS from a static system to a dynamic system.
DNS Configuration
The domain name system (DNS) is a static, hierarchical name service for TCP/IP hosts.
The network administrator configures the DNS with a list of host names and IP addresses.
This allows users on the network to query the DNS to specify remote systems by host
names rather than IP addresses.
