I had the domain hosted on an hsphere test acct. I deleted the acct and recreated the site under a non-test acct (same ns info and everything. Nothing changed there). I can access the site immediately via http://domain.com but not via www.domain.com.
Im guessing the www dns entry was deleted and must be propagated again??? Anyone else that is the case?
Go to the /var/named directory and edit the file for the domain. Add in the www line and restart bind (service named restart) and you should be good to go. There is no need to way for nameserver propogation if the domain is already going to your server.
