dns problem

[Gregory Nowak]

Yeah, if your isp or whoever you registered your domain with, knows your ns1 machine by one name, and you decide to give your ns1 another name without telling them, you're going to have problems. Either contact your isp and whoever you registered your domain with, and give them the new name for ns1, or make your new server have your old server's name.

I never saw the advantage of naming your dns servers as ns1.domain.com, but I think I do now (smile).
