I have been having connectivity problems with the Macs that are on my network. They keep dropping on and off the network, they get the error message "Access to your appletalk network has been interrupted. When the network becomes available again, a message on your screen will notify you."
Also the PCs do not appear to be having any problems. This problem has seemed to get progressively worst over time. We have a Cisco 3500XL switch, that had just been replaced under warrenty about 5 months ago. The Macs are running OS 9.2.2, HP server Win NT 4.0, Nics are AsanteFast 10/100 PCI using most current driver 4.0 They are set at Full duplex and 100 mbps on Macs and on switch, I have also tried auto negotiate. Are there any diagnostic tools built-in to this Switch? I'm currently using netscape to configure switch. I would greatly appreciate any help you could offer.
