Please go to the DreamHost Web Panel's Domain > Web area and click the [Edit] link next to domain.com to re-configure cloaking.
That part of the message is the hint, though you don't want to re-configure it as "cloaked"; you want it to be "fully hosted" (I assume). 
Go to the Control Panel -> Domains -> Manage Domains screen and click "edit" in the "Hosting" column for the domain.
Complete the "fully hosted" section (set options as desired), then "save" it (submit the form by clicking "Change fully hosted settings now", and give it some time to take effect.
That should "regenerate" the fully hosted status of your domain.
