The department is using the Ethernet NIC for its own use, and the PCNET was connecting the department to the rest of the campus. For unimportant reasons, we had to disconnect the PCNET side of the server leaving the wire unterminated (not good practice I know.) A little later, we tried logging in to a few other machines, and repeatedly got the "A File server could not be found" message when running NET3. I immediately plugged the PCNET side of the server back in, and everything worked fine. (No more problems) The only strange thing I noticed was that we have another department running with two PCNET cards in one server (One for a local PCNET network), and it works fine when the Primary (LAN A) NIC is unplugged. Very strange. I hope this helps. Doug Wilkinson Computing and Information Services Brown University
