I would not have done that until I had the box running with all the bugs

I am taking a guess here because I am fairly new at this Kerberos stuff,
but I think that the database is built around the realm name that you give
kdb_init.  

The best quick fix solution would be to change everything back in the
kerberos settings to use the old MEGAHITS.COM realm name.  Configure your
/etc/krb.conf to point that realm to your kerberos server.  From there you
will need to dump the database into the new database.

PLEASE note that I have GUESSED at this solution.  I am interested in
knowing more about how the database is built.  I do not know that you need
to dump the database, but I am confident that you can get the server
running again by changing things back to the way they were.  The only thing
that needs to be configured to domain megahits.net is the machine via the
rc.d files.  You can call your Kerberos realm what ever you want just make
sure that it is your default in your /etc/krb.conf file on all the machines
your are using that REALM.  {More detailed stuff is possible with the realm
listings, but you have stated that all you want this to do is work}
