Well, in the PDC/BDC scenario, all you get is a "high avaliable"
logon service, but not file or print services. 

I would suggest looking into
and make the samba service itself high available. There already is some
early software to exchange heart-beat between two server so the backup
will start its application and switch its IP number once the primary
server goes down.
