I have a bit of a problem that I can't seem to get a handle on. We have 150 domains hosted on our dedicated server. Our ISP provides name servers for the server and some of the domains. The other domains are registered and have DNS services elsewhere such as tucows and godaddy. Account primary Domains themselves do not seem to be a problem. Parking a domain that has DNS provided elsewhere is causing some hiccups. If I use WHM to park the domain - it works fine. If I use the cPanel control panel to attempt to park it, Park Domains says to add xxx.xxx.xxx.xxx, yyy.yyy.yyy.yyy name servers and refuses to add the parked domain. I am a bit confused as to what is happening here. Can someone explain why one method works and the other does not. Why would I be required to enter the IP addresses for nameservers provided by a third party?
