Beating head on desk again!

I have a samba server is running winbind which can access domain.  It is
working fine and is using domain credentials.  I access the samba shares
after the user has authenticated against a novell server during the novell
logon script. The shares are authenticated with user domain credentials and
verified with smbstatus. This works great!

If I alternatively use windows networking domain authentication, I have
The Win95 station correctly authenticates against NT4 PDC and runs logon.bat
from that server. 
As LOGON.BAT accesses samba shares, samba appears to get user credentials
without the Domain Name.  Since there are no users on the samba server, this
gets morphed into nobody.  
All services which can be accessed as nobody are attached as nobody,  all
other services are denied.  As a result important tools such as "net use X:
/home" do not work when file and directory permissions prohibit access to

During the LOGON.BAT, I issued a net config
Computer name                  \\LGA00D0B724628B
User name                      GPALMER
Workgroup                      LGANET
Workstation root directory     C:\WINDOWS

Software version               4.00.950
Redirector version             4.00
Client for NetWare version     3.26

Registry setting require authentication..  It appears that "net" thinks it
is part of the domain; but as stated above, samba attaches as nobody.  Samba
logs indicate that it is receive user gpalmer and not lganet\gpalmer. 

>From a DOS window, after logon.bat finishes , I can successfully execute
"net use X: /home".  Samba gets and processes the full domain credentials.  
Samba interperets user as nobody without regard to setting in "Log on to
windows nt domain" in the "client for microsoft networks" dialog.
If the home directory is moved to nt server it will successfully attach
during logon.bat.
I have exhausted all options I know about.

Thanks in advance for any insight you might give.
