Microsoft Network card shows not connected when really it is
Posted on 2011-03-22
Hi, i have an application which buffers network traffic in the case of a comms outage, when we reconnect the network (turn on the switch) we are finding a random machine (5 connected to switch) will have its nic card status showing not connected. If i go into Network Connections and disable and re-enable the card, normal service is resumed.
Does anyone know why one NIC card seems to go down each time we reboot the switch, i assume the sudden flood of messages is causing the crash. Is there anything in Windows i can change to try and fix the problem?
