[Samba] access samba 3.0 shares from Win2K, Win3K, WinXPProf. using netbios name

Hi:
  I have a Windows 2003 Server Enterprise Ed. as Domain controller, an
its 

current domain functional level is 'Windows Server 2003'.
Also, I have a RedHat Linux 7.3 server with SaMBa (tested with rpm 

samba-3.0.0-2, and compiling the samba source code).
I'd joined the linux server to the AD tree without problems, access from


it to the Win2003 shared resources too, but I have problems when try to 

access to the SaMBa resources from the Win2K, Win3K, WinXPProf machines.
The things I can do are:
 - obtain a kerberos ticket: kinit ADMINISTRATOR@DOMAIN
 - join to the domain using this ticket: smb ads join -k
 - obtain a domain user or group list: wbinfo -u/-s
 - obtain an entire list of the users or groups (Unix+Domain): getent 

passwd/group
 - access from linux server with the kerberos ticket to the Win2003
Server 

shares: smblicent //SERVER/share -k
 - Access from Win9x/WinMe/WinXP Home clients to the linux/samba shares,


using the linux name or ip, with the network browser or the net use 

command.
 - Access from Win2K, Win3K, WinXPProf clients to the linux/samba
shares, 

ONLY USING THE LINUX IP with the network browser or the net use command 

(net use * \\ip\share)

Things I CAN'T do:
-----------------
 - Access from Win2K, Win3K, WinXPProf clients to the linux/samba
shares, 

ONLY USING THE LINUX NETBIOS NAME with the network browser or the net
use 

command (net use * \\name\share)
 - access from linux server with the kerberos ticket to the linux+samba 

shares: smblicent //SERVER/share -k


The problem seems to be in the client access to the samba shares with th


kerberos ticket authentication.
When a win9x/winME client access to a share, the authentication mode
used 

is NTLM, and I have not problems with it, and occurs the same ussing the


IP instead the name with any client.
When I use a kerberos ticket obtained in the linux machine to access 

win2003 resources, I have no probles neither.
But when I try to access linux shares with the kerberos authentication 

method, I have problems.

How can I beat this problem??
