samba - Jun 2007 - Problems with trust relationship between Samba 3.0.25 & Win 2k3

Hi,


I'm trying to setup a trust relationship between a samba 3.0.25 
(172.16.5.2) and a Windows 2k3 (192.168.10.7).

Here are the details:

/opt/samba/lib/smb.conf
--------
[global]
         workgroup = ESSVW
         netbios name = ESS-PDC
         server string = Linux BSZ-PDC ESS
         log file = /var/log/samba/%U.log
         max log size = 0
         log level = 5
         socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
         logon script = %U.bat
         logon path = \\%L\profiles\%U
         logon drive = Y:
         domain logons = Yes
         os level = 128
         preferred master = True
         domain master = True
	wins support = yes
         remote announce = 172.16.5.255/ESSVW
         idmap uid = 10000-20000
         idmap gid = 10000-20000
         winbind uid = 10000-20000
         winbind gid = 10000-20000
         security = domain
         winbind cache time = 10

The name of the windows machine is BSZ-VW-ADS1 the domain name is DOMVWBSZ.

/etc/resolv.conf
------------------
namesever 192.168.10.7
search domvwbsz.local

/opt/samba/lib/lmhosts
-----------------------
192.168.10.7    BSZ-VW-ADS1#1B

------------------------------------------------------
"net rpc trustdom establish domvwbsz -I 192.168.10.7" tells me, after
I
entered the right password:

Could not connect to server BSZ-VW-ADS1
Trust to domain DOMVWBSZ established

------------------------------------------------------
And "net rpc trustdom list":

Trusted domains list:

DOMVWBSZ            S-1-5-21-1182609643-415455094-2933463074
none

Trusting domains list:

DOMVWBSZ            S-1-5-21-1182609643-415455094-2933463074
Unable to find a suitable server
domain controller is not responding

------------------------------------------------------
Let's check the DNS:

nslookup BSZ-VW-ADS1
Server:  bsz-vw-ads1.domvwbsz.local
Address:  192.168.10.7

Name:    BSZ-VW-ADS1.domvwbsz.local
Address:  192.168.10.7

------------------------------------------------------
nslookup 192.168.10.7
Server:  bsz-vw-ads1.domvwbsz.local
Address:  192.168.10.7

Name:    bsz-vw-ads1.domvwbsz.local
Address:  192.168.10.7

------------------------------------------------------
I have already set up the trust relationship on the windows server.
But why isn't the samba server able to find the DC but claims to have 
established the trust to the windows domain?

Thanks for any hint and advice,

Stefan
