I've tested this in a similar environment, and my experience is this:

- If you use different netbios names, you must use 2 different secret.tdb
  files (or re-join the server to the domain after each fail-over)

- If you use the same netbios name, you can (must?) use the same
  secret.tdb file on both physical nodes.

- Remember to use "bind interfaces only = yes" when you bind to a
  virtual interface.

I'm not sure if you may experience some kind of "timeout" if you use 
different secret.tdb, and the service doesn't fail over for a long time.

I don't think there has to be a relationship between the DNS name of the
virtual interface and the netbios name.
