Examples of Dynamic DNS Host Name Registrations

By default, a computer running Windows 2000/XP registers only one name in DNS, which is hostname.PrimaryDNSSuffix, for example bob.chicagotech.net. However, if you need the computer to register temporarily in a Domain Name Server child domain (for example, you travel to a different location of your company and like to register on the local network), how do you register the host name?

This article gives some DNS registration examples.

1. If the computer is to register it’s host name only in the Domain Name Server subdomain zone, for example ms-mvps.chicagotech.net, you need to change the PrimaryDNSSuffix of this computer.

To change the computer's PrimaryDNSSuffix:

1.	Click the Start button, point to Settings, click Control Panel, and then double-click System.
2.	Click the Network identification tab, click Properties, and then click More. Type the new domain or subdomain for this computer in the Primary DNS suffix for this computer box, click OK, click OK, and then click OK.

2. If a computer is configured only for the parent domain:

•	The "Primary DNS suffix for this computer" setting is set to domainname.
•	The "DNS suffix for this Connection" setting is set to child-domain.domainname.
•	The "Register this connection´s addresses in DNS" setting is enabled.

3. If a computer is configured in both the parent and child Domain Name Server zone files:

•	The "Primary DNS suffix for this computer" setting is set to domainname.
•	The "DNS suffix for this Connection" setting is set to child-domain.domainname.
•	The "Register this connection´s addresses in DNS" setting is enabled.
•	The "Use this connection´s DNS suffix in DNS registration" setting is enabled.

4. If a computer is configured only for the child domain:

•	The "Primary DNS suffix for this computer" setting is set to child-domain.domainname.
•	The "DNS suffix for this Connection" setting is set to child-domain.domainname.
•	The "Register this connection´s addresses in DNS" setting is enabled.
