I have an intel core 2 duo system intend using as an internet server. I have installed Wins server 2003 ans ISA on it, the board came with a 10/100mbps network card, now i added a 100/1000mbps network card to make the cards to be 2, but the problem is whenever i configure this cards and give then an ip adresses, one of the network cards will automatically be unpluged, i have tried it on another system it does the samething, i changed the cards to the same specs it still does the same thing. what i discover is that when i put this cards on a normal windowsXp sytem it works perfectly. Now i am really confussed, anybody with help on what to do? i need it urgently.
