I have Server 2008 and I want to access my web site without having to use www in front. CNAME won't accept a blank entry (http://mydomain.com), when I try I get an error of "A new recored cannot be created. An alias (CNAME) record cannot be added to this DNS name. The DNS name contains records that are incompatible with the CNAME record.".
The only things I have I have associated with CNAME in my domain name is my exchange, my AD as name server, and my web box as www referencing it's internal name.
