If you can't, the problem can be in the domain dns with your registrar (for example, eNom or GoDaddy) or in the ispcp configuration, check /var/cache/bind/ do you have a file there like "yourdomain.tld.db" ?

I can it works, but i'd like to know more what works where and how, so i can bug you ppl less ;-)
