[Samba] Error connecting WinXP client to Samba PDC: DNS name does not exist / RCODE_NAME_ERROR

[Christian Geiger]

Hi!

I so far succeeded in setting up a Samba NT4 DC with OpenLDAP backend. 
Unfortunately I get the following error message connecting a Windows XP 
client to the domain (translated from german):

[...]
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.lohrmann.de
[...]

This is surely due to a problem in the name resolution. I therefore 
configured the Samba server as a WINS server and checked that it is the 
only one on the net. The WinXP client has been told to use this as its 
WINS server and has additionaly been supplied with entries in the hosts 
and lmhosts configuration files (step by step, always testing in 
between). Unfortunately, this changed nothing. :(

Unsucessfully seeking for a solution on the web for quite a time now I 
would be very grateful if someone could help me!

Find below my smb.conf, the hosts and lmhosts file from the WinXP client 
as well as the console ouput showing some NetBIOS information of client 
(emco-test) and server (domain-controller).

Thank you very much in advance! :)

Chris
