How To Configure DNS Domain Name System In Server 2003
ADS uses Domain Name System (DNS) to locate resources on a network. Without a reliable DNS infrastructure, domain controllers on your network will not be able to replicate with each other, your clients will not be able to log on to the network, and Microsoft Exchange Server will not be able to send e-mail. Essentially, if your DNS implementation is not stable, your Windows Server 2003 network will fail. This means you must have a thorough knowledge of DNS concepts and the Windows Server 2003 implementation of DNS if you are going to manage a Windows Server 2003 Active Directory environment.
We have installed DNS Server during the ADS configuration wizard. But if you have skipped the configuration of DNS Server at that moment see our previous article to install it from the control panel.
To configure DNS server
Click on start button select administrator tools and click on DNS
If you do not see the DNS option in Administrator tools submenu it means you haven't installed it. See our previous article to installing it.
In left pane expand the Server. Here you can see the default forward and reverse zone which was configured during the ads configuration. Delete the defaults zone files.
Make sure you remove both forward and reverse lookup zone files before start configurations
Now we will create new forward and reverse zone file for DNS.
Right click on forward lookup zone and select new zone files
Click on next on welcome screen
Select the primary zone.
We need not to store zone in ADS so Remove the check mark from Store the zone in Active Directory
Give a relative name for this zone file. For local network we suggest you to give your domain name for this zone file.
Our domain is Example.com so I set Zone name to Example.com
We are creating the first zone So select Create a new file with this file name, do not change default name just click on next
We are going to use this DNS server in local network so select Allow both nonsecure and secure dynamic updates. Don't use this option in public network.
On the summary table just click on finish
