As in: I have a domain called mydomain.com. I have a box called mybox.mydomain.com. I have a A record in my ISP's zone file for mybox.mydomain.com I can not resolve mybox.mydomain.com to an ip. Should mybox.mydomain.com be a CNAME record? Any help will be greatly appreciated. Mike Dewhirst This message was written in plain text mode.
