I found that notebook Dell D600 has similar network card. But I cannot replicate the issue at D600; the same network, the same server, the same network cable... NetXtrema card in D600 works, but similar card in NC6000 is troublemaker. Network chip used in D600 is different from the one used in NC6000.
