if you're not already doing it, you can point your system to the domain name server that your name is set on, it should be able to find it that way. i had to do that once, until everything propogated. that sucked
i.e. if your domain service's main dns is dns1.poop.com then add that as a domain name server on your own computer. it really won't bother anything, i'd make it primary. you can change it back if you want to, but there's really no reason to.
