About Name Resolution
In order for people to reach your site on an intranet,
you must have a unique IP address that identifies your
computer on the network. This address takes the form
of a long string of numbers separated by dots (for
example, 172.16.255.255). Because a numeric address
is difficult for people to remember, text names or
“friendly names” are used to provide visitors with an
easy-to-remember address, such as \\MyStoredFiles.
Name resolution involves interpreting the correct
numerical address from the friendly name that was
typed into a client browser. This section describes
different name resolution systems.
The use of an LMHOSTS file is optional. If an LMHOSTS
file is not used, users cannot use “friendly” text
names instead of IP addresses. This can be a
disadvantage because Web sites on the Internet
usually use the Domain Name System. If you register a
domain name for your site, users can type your site's
domain name in a browser to contact your site.
The LMHOSTS file is read when WINS or broadcast
name resolution fails, and resolved entries are stored
in a system cache for later access. When the computer
uses the replicator service and does not use WINS,
LMHOSTS entries are required on import and export
servers for any computers on different subnetworks
participating in the replication.
You can use Microsoft Notepad or any other text editor
to edit the sample LMHOSTS.sam file that is
automatically installed in the \Windows directory. The
following rules apply for entries in the LMHOSTS file:
