[Samba] Error joining domain samba 3.0rc1

[Jarabe]

This is the error i receiving now when I attempt to join the domain.

The domain name samba might be a NetBIOS domain name.  If this is the
case, verify that the domain name is properly registered with WINS.

If you are certain that the name is not a NetBIOS domain name, then
the following information can help you troubleshoot your DNS
configuration.

The following error occurred when DNS was queried for the service
location (SRV) resource record used to locate a domain controller for
domain samba:

The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.samba

Common causes of this error include the following:

- The DNS SRV record is not registered in DNS.

- One or more of the following zones do not include delegation to its
child zone:

samba
. (the root zone)
