Checklist: Create an Alias (CNAME) Record
Applies To: Windows Server 2008, Windows Server 2008 R2
With alias (CNAME) resource records, you can use more than one name to point to a single computer. For example, you can use an alias (CNAME) resource record to allow a server named webserver.contoso.com to also be known as www.contoso.com.
