You may need to experiment with different variations on the dcDNS variable
and you may need to remove the ServerBind flag if you are using a NETBIOS
name. Also, you may need to remove the Sealing flag as well, but be warned
that in order to set or change passwords, some sort of encrypted channel
(SSL or Kerberos) must be available.
