What I would like to know, and what nobody can answer is, What in the heck could 0.0.0.16 be? The big issue right now is that the Ultra 5's won't mount the NFS volume, but I don't think it's related to this question. Since the Ultras won't mount the NFS volume from the 450, could a cd be exported as NFS and jumped by an Ultra from a Linux machine? Thanks, Bill
