I have a school I service that is trying to improve the quality of their network. They have replaced a couple 10 Mb hubs with a pair of Cisco 2950 switches. I am not entirely sure if they don't have a loop going on, but now their appleshare servers and printers drop off randomly, with no apparent pattern. Any ideas why this would be, or if a person should add anything to the switch config to aid in helping appleshare work correctly?
