samba - Sep 2005 - Yelling for help on interdomain Trust (a long one)

Hi there,

Scenario:
Domain A: Win2000Server(PDC)(DC1) + Win2003Server (DC2)
Domain B:Samba 3.0.20 (compiled with the patches from
http://us1.samba.org/samba/patches/)
Where Domain A is the TRUSTED domain whereas Domain B is the TRUSTING
domain.

And here is part of my smb.conf:

My journey to setting up the trust:
1. Create Domain A account in Openldap --> smbldap-useradd -I "Name of
Domain A"
2. Create trust on Domain A (DC2) --> added "Name of Domain B" and
assigned
password and valid the trust --> No error message
3. establish the trust on Samba --> net rpc trustdom establish
"DomainA" -U
administrator, then password


My problem:

1. I was prompted with the following error:

	Could not connect to server DC1
      Trust to domain DomainA established

2. joined a workstation (WinXP SP2) to Domain B, can see Domain A and Domain
B in the list. Logged on as DomainA users

3. Some of the workstations can log on, but no login script from Domain A is
loaded (error log Event view said that cannot contact DC1), but can manually
mount the network share

4. Some of them simply blue screen to death with winlogon.exe error 

5. No problems from Users in Domain B, network shares/printers (from Domain
B) is working fine


Some more info:

1. The trust was working before until Win2k3 was introduced to Domain A

2. Samba.3.0.14a + Win2000Server combination was OK

3. The trust worked once under Win2k3 SP1 + Samba.3.0.20 with "client
schannel = no" but malfunction when I came back to office after the
weekend.


Hope someone (especially the SAMBA Team) can help me out.


THX and appreicate with the help
