Just looked up your domain:
Domain Name: DANRIPPON.COM
Registrar: NEW DREAM NETWORK, LLC
Whois Server: whois.dreamhost.com
Referral URL: http://www.dreamhost.com
Name Server: NS1.DREAMHOST.COM
Name Server: NS2.DREAMHOST.COM
Name Server: NS3.DREAMHOST.COM
Updated Date: 10-oct-2007
Creation Date: 10-oct-2007
Expiration Date: 10-oct-2008
That looks correct, but your domain is not in the DH nameservers.
While there is anecdotal evidence forcing an update from the control panel may get you on-line, I suggest opening a support ticket.
Another customer had a similar problem recently. If support gets enough problem reports, DH may track down whatever script is causing this problem.
