Hi, never used freebsd, but 4.2 is not just an AD DC, it is also 
supposed to be a replacement for the old 3.6 series and work in the same 
way. There are some changes to what can and cannot go into smb.conf, but 
these are minor and can easily be identified by reading the smb.conf 
manpage and the samba release notes.

Does anything start ?
Is there anything in the log files ?
what is your smb.conf ?
