I've tried re-installing DECNET from tape, but that doesn't seem to work, as it says DECNET is running and must be shut down first. So how do I: a) Set the node name / number of a previously installed DECNET install This is a guess, as I've done very little DECnet under RSTS/E, but possibly try: $ @decnet$:net cfg $ @decnet$:netcfg $ delete/nolog/nowarnings dnet:addcrc.dat ^ ?Not a valid device Before you ask, yes. I eat logicals for snacks it would seem. b) Shut down the DECNET process so I can reinstall Try: $ ncp set executor state off That MIGHT be enough. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
