I'd treat it like any other NT box, which is to say that *I* wouldn't
put it directly on an untrusted net.  If all you want to do is provide
Winframe, one approach would be to put a second ethenet card in the
machine and connect it to the untrusted network through a filtering
router, letting only the ICA port through.
