Cannot log in DOMAIN from NT workstation

[Vadim Kimlaychuk]

    I have samba-tng-2.1. After I've configured smb.conf (it exactly the same as example on www.kneshke.de/../pdc.tar.gz except workgroup) 
than created trusted account computer_name1$ and user accounts administrator and K2, then added to smbpasswd administrator and K2 , and enabled them
and launch 
 smbd -D
 nmbd -D
NT workstation (computer_name1) cannot log in! 
 In log.smb I've found:
- administrator password doesn't match LANManager - connection failed.
- no trust account for computer_name1$              
   ?????
