Do you have other reasons to believe this, or just that Samba uses

Samba, as of 2.0.7, does not send or receive NetBEUI at all.  In fact,
I don't think most versions of Unix even support NetBEUI, though I
suppose you could do something with raw sockets.  (I'm a lousy sockets
programmer so I'm not sure about this.)

Samba will gain NetBEUI functionality at some future date.  It has been
written already.

Strange.  Very strange.
