W2K Domain Login Problem with 2.2.0

[Chen Shiyuan]

Hello!

I was using samba-2.2.0-alpha3 (and just about earlier versions as well) 
and had no problems with getting W2K users to login to my domain using 
their username/password.

However, after upgrading to samba-2.2.0, when W2K users tried to login 
using their username/password, W2K pops up a small dialog box in the 
middle of the screen that says - Your account has been disabled, please 
contact your System Administrator.

But when I use the W2K's local account to login to the W2K and try to 
browse the Samba-2.2.0 server, it prompts me for a username/password 
which authenticates just fine and I am able to browse the server's 
shares. I am also able to join/leave the Samba-2.2.0 domain without 
problems. The only problem that I have encountered till date is that the 
users are not able to do a domain logout due to the above error message.

The same problem occured irregardless of whether I am using the Redhat 
6.2 Samba RPM binary file or compiled samba from the tarball.

After I switched back to using 2.2.0-alpha3, users were able to login 
again just fine. The smb.conf file, smbpasswd, MACHINE.SID, etc were 
left unchanged when switching from 2.2.0-alph3 to 2.2.0 and back.

Also, occasionally, the following pops up in my smbd.log file :-

Does anyone know what is causing the above problems? Can someone help me 
out in this? Do I need to provide more details?

Many thanks in advance!
