At the school where I provide technical support we have two building on the same network. We had a power outage due to a storm over the weekend and we now have several systems in one building that cannot connect to the network. The building where the server is housed is OK but the other building has about half the systems no longer able to connect. Each building has its own 28 port switch that handles the network connections. Is it possible that the power outage caused a surge that damaged some but not all of the ports on the switch or should I be looking at some other problem?
