we're trying to add an MX record to a Windows Server 2003 DNS server and getting the following error:
"A new record cannot be created. Node is a CNAME DNS record."
The domain is xyz.com. We create a new MX record and leave the "Host or child domain:" field blank, then we're putting "cluster122.us.messagelabs.com" in the "Fully qualified domain name (FQDN) of mail server:" field and leaving the default Priority of 10.
Are we missing something?
