I use DH only for hosting, not DNS.
I've hosted example.com and test.example.com and they all work fine.
When I add aa.test.example.com to my DH, this came up:
====================================Site Temporarily UnavailableWe apologize for the inconvenience. Please contact the webmaster/ tech support immediately to have them rectify this.
That's telling you that the server's not configured properly. Send a support ticket in and DH can take care of you.
================================I'd give my right arm to be ambidexterous!
Is the sub-sub domain one of the special reserved names?

I've fixed this error.wildcard DNS configured this sub-sub domain to a certain ip, but it seems that DH will assign a different ip when i add a new domain.
Unless you asked DreamHost to enable wildcard DNS for you, and they did it, that statement is not accurate.
