okay, now we're getting down to it. sometimes it's tough just to figure out how to ask the question you want to ask. you say this:
yes! I assumed this was the problem. Then you say this:
okay, so I create a new DH sub-domain called mysql.mydomainname.dreamhost.com? Where I point it to and what the impact is, that's where my understanding ends. I would think I should point it to mysql.mydomainname.com, but I don't really understand what's happening when I do that. Am I creating a unique dns entry somewhere that identifies mysql.mydomainname.com as being on DH servers?
