Help Win2000 cant join samba domain

[El Mamouni Saïd]

Hi

I have a new computer with win2000Pro and i want to join my samba domain.
I give to this computer the same name as an old one who was under 
WinNTworstation (same name, same IP)
When i want to join the domain he tell's me an error about the map of login 
and the security ID

I have modified the reg file, i'm under Win2000 SP2

in the smb.conf i have :
admin users = root admin
When i want to join the domain i use the admin login

thank for your suggestion.
