I need your urgent help. I am configuring windows 2003 server. The server has two NIC cards on it. I gave two different IP address with the same subnet mask. 192.168.0.2 and 192.168.0.3.
I have small LAN. Network cable is plugged in to the one NIC the other left open. Before installing DNS server it was doing good. After installing DNS I couldn’t connect to other servers. When I disabled the unplugged NIC card it works when I let it enabled it didn’t work.
Don't assign IP addresses belonging to the same subnet to different adapters as the machine will try to send all outgoing traffic to that network using the adapter with the highest metric or that is highest in the adapter binding order, and this will give the symptoms you described above.
If you need to assign more than one IP to the machine in the same subnet, you can add multiple addresses to one Ethernet interface using the advanced options in the TCP/IP properties dialog.
