[Samba] can not access samba drive on Redhat ES 4

[Kathy Khagani]

Hi,

Our samba server is running  Red Hat Enterprise Linux ES release 4 (Nahant Update 4) with samba version: samba-3.0.33-0.17.el4.  We like to authenticate all the users with our Primary Domain Controller wnidows 2008.  Some users keep getting asked to enter username and password. Even with the correct password, still can't access the drive.  The strange thing is that some users are successful.
These users all have valid accounts on windows.
In this case user "jrau" is a valid user and "JRAUXP" is the PC name from which he is accessing the samba share.

Wbinfo -u   displays his username:

STEC-INC=jrau

But not the computer name, which makes me think that might be the problem.
Also we are not using LDAP, just winbind.

Here is some my config files and error logs:
