If you've ever had two lan cards installed in a single System using windows 2K, you might have run into this problem. I've seen other systems do just fine, so I'm not sure what's up, but if any of you have suggestions, I'm open!
Problem: A single processor Windows 2000 Standard server has two NICs - one is a built-in gigabit ethernet and the other is a generic 10/100 PCI card. The built-in NIC is setup for a LAN on 10.0.0.X with a subnet mask of 255.255.0.0 and the PCI NIC is setup to connect to the internet via DSL, with DHCP usually assigning a subnet of 255.255.255.0.
Upon boot, no errors. When you attempt to connect to the internet, you wont get anywhere until you first disable the internal card - type in the URL and then you will connect. You can then re-enable the internal NIC (the gigabit card) and your LAN will function. Every so often, I have to disable the internal LAN to get the internet browser to recognize the internet facing NIC.
What gives? This is driving us nuts!
