Thanks for the reply. The error is displayed anytime you try an use the network, IE ping to default router from the command prompt. I now longer have access as it is the USA and I am in the UK, the networking is no longer woring from the system, I have asked the local person to change the network card, but that still gives the same error. Weh you go an IFCONFIG no errors are reported and the link light is on all the time, and the activity light does flash. Denis
