error 86 : bad password

[bat-dan at ifrance.com]

   I'm currently trying to install samba 2.0.3
following DIAGNOSIS.txt on Solaris 2.7
   When I try "net view \\ampere" ( ampere = samba
server ) I got the following : Error 86 ... bad
password ( in french : erreur 86 , mauvais mot de
passe, contacter votre administrateur reseau...)
  what can I do ? I believe the error comes from the
smb.conf but I tried several changes and none were
useful. 
            Thanks for help !
Baptiste.
