Unable to find out which user owns the parked domain

Manually unpark the domain ...

I would grep the /var/cpanel/users folders for the domain
that you are looking for and remove it from the user file in
question (this will also tell you who owns the domain).

Remove the domain entry from /etc/named.conf and
the cooresponding .db file from /var/named and restart
your bind server.

Remove the virtual host or ServerAlias (whichever is applicable)
from the /etc/httpd/conf/httpd.conf file and restart Apache

Remove files with that domain name as the filename from
/etc/valiases, /etc/vdomainaliases, and /etc/vfilters.

If the domain is in /etc/localdomains or /etc/remotedomains then remove
it from those files as well. Same goes for /etc/userdomains

This should pretty much wipe out the domain and you can re-add it whatever
account you wish if that is want you want to do or just leave it gone!

 

:D Excellent. This worked perfectly!
