[Samba] smbclient

[Ria]

Hi!!
I'm having a slight problem here
This is the scenario
W2K and NT can access samba server.
Samba client cant access W2K and NT shares.
Gets an error message "NT_STATUS_LOGON_FAILURE"

Note..Samba can list its own shares using smbclient but not of W2K 
and
NT.

smbclient -L <W2K-PDC> -U administrator
lists all the machines in the domain but not the shares.

NOTE: Samba is not added to the Domain (i.e. smbpasswd -j..... has 
not
yet been run)

Plz help

regards,
ria
