Ayuda con samba

[Dario Muriel <dmuriel@venks.com>]

Hola,

Este es mi primer post
Llevo unos dias intentando hacer funcionar samba con windows XP y nada :(
cuando pongo en windows la ip del linux me llega a pedir el password y user 
pero no llega a dar ni error ni ok, vuelve a pedirlo una y otra vez
si intento mirar q esta compartido con el smbclient me da este error


=================================================
xbox:/var/log/samba# smbclient -L localhost -U test
Password:
session setup failed: NT_STATUS_LOGON_FAILURE
=================================================


El test parm me da lo siguiente
==================================================
xbox:/var/log/samba# /usr/bin/testparm
