Accesing Computers / joining Domain fails due to DNS

[Thomas Felber]

Hi everybody,

i want to set up my server as Domaincontroller for my Windowsmachines. I
think Samba-Configuration is fine.

The required files are uploaded on http://thomas-felber.de/DNS/

Everytime i want to join the Domain I got the following DNS-Error.

The domain name dschungel 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
dschungel:

    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.dschungel

    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:

    dschungel
    . (the root zone)

    For information about correcting this problem, click Help.

Some configuration files are attached.
Thanks for any help in advance.

Thomas


PS: named-checkzone says OK
      named-checkconf says OK
      ping with any hostname works fine
      but Using "\\grissom" in Start--> Run says "Not found"
