I have a network of 17 computers. I’m running windows xp on all of them. They all connect to the internet through a 24 port 10/100mbps Nway switch. A few days ago i started having some problems; some computers could not access the net. I checked the switch, and it was showing that some of the computers were not connected to the network. On some of the machines, the network icon in the system tray connects then immediately disconnects, then tells me that a network cable is unplugged. This is happening with 6 or 7 machines. Any help would be appreciated.
