Evidently, a sub-domain takes a whole lot longer than the documentation says that it should take. After a couple of hours I tried again and was finally able to connect to the page to populate the db.
I am trying to make the mysql work by mirroring the domain with a sub-domain and not pointing my old site on another server. I must make certain that the site works as it's supposed to do prior to moving the namerserver pointers. My entire site is dependent upon mysql in order to display.
Thanks for your help. I guess I was too hasty in expecting the sub-domain to respond after creation. But the docs of DreamHost indicated that it would only take a few minutes.
Be gentle with me... retirement is right around the corner
