NT machine account

[Jonathan Lee]

Hi,
I want to set my Samba server as Domain PDC.
I follow the following step to add my machine account to smbpasswd
1. Create an account called EE1$ (passwd is ee1)
2. use smbpasswd -a -m EE1

When I want to change my domain to that Samber's domain, the error message
popup on Windows NT WorkStation is "The machine account for this computer
either does not exist or is inaccessiable"

BTW:
I can access the share from that Samba server, including the netlogon
