Yup. Something else I just noticed that *might* be important...

That says that ws.linuxlighthouse.com is the one and only name server for the domain. Whereas whois shows the more normal 2 minimum:

>whois LINUXLIGHTHOUSE.COM | grep ^Name
Name Server: WS.LINUXLIGHTHOUSE.COM
Name Server: NS3.ATTDNS.COM

So, even if you let NS3.ATTDNS.COM pull the zone from you it might not work correctly if they just use the zone you feed them without adding themselves to the mix with an NS record.
