Prepare your environment for Windows Server 2003 DNS deployment by ensuring that you have reliable backups of anything that you plan to change, including servers and zones. Test your backups before you proceed with your deployment. In addition, create a recovery plan for contingencies such as data loss, server failure, and failure of network connections.
Before implementing your DNS deployment, ensure that routing links between the servers that you plan to deploy are in place and are working correctly. Depending on how your DNS infrastructure is configured, your DNS servers might need to query the following:
Servers hosting parent zones.
Servers hosting child zones.
Servers on an external network or the Internet.
If you expect clients to query for names on the Internet and you plan to use a proxy server, ensure that the proxy server is in place and that a proxy-client/firewall-client is installed on the client. In addition, ensure that the Web client configuration is set in a Conseil Européen pour la Recherche Nucléaire (CERN)–compliant Internet browser. Microsoft Internet Explorer is an example of a CERN–compliant Internet browser.
