Once in a while, some of my users loose connection to the network. I don't see anything in eventvwr (NT 4) on my servers. I'm not using network monitor because it takes up to much juice out of those old servers. One thing strange I notice last it hapens is that all the Packect lights on the 3Com SuperStack III switch. Correct me if I'm wrong, but usually, when it flashes on every port, it means that it is a broadcast. But when the users are disconnected from the network... that switch keeps flashing on the broadcast port for a couple of minutes. Then it goes back to normal and users can have access to the network.
Is this a bottleneck problem?
