I have a LAN set up in which I am running MacIntosh computers through Cisco Fasthub400 and Cisco 2900 switch and connecting to a MacIntosh Server as well as a Netware 5.1 server. I am attempting to use an Apple program called Network Assistant to remotely manage my Mac workstations but seem to be having a problem with the sitch setup. I have been told that the switch needs to be set to half duplex with Spanning Tree Portfast disabled. Can anyone elaborate on this for me. Thanks.
