[Samba] Please help to add a machine to a domain

[Pavel Stulik]

Hello,

could you please help me to solve the following problem:
When I try to add a machine to a domain from winNT, I get the following 
error:
Unable to add or change accounts on the domain. The account information 
entered does not grant sufficient privilage to create or change accounts.
The whole process create an unix account (machinename$ in /etc/passwd) 
as well as samba account (machinename$ in /etc/samba/smbpasswd) but 
samba accont has password "NO PASSWORDXXXXXXXX".
Do you have some idea where is a problem or how to get around it?

Thank you.

Pavel Stulik
