Hello ,
I have two router as well as two switch. 1st router is Dlink's router, I used this router for sharing files and folders and also connect to NET. And 2nd router used for Windows Media Encoder to upload my audio data to other computer.
My first router is connected with a 16 port DLink switch, and also 2nd router is connect with another 8 Port Dlink router. Now, 1 computer has two LAN card and it connect with both router through switch. But both is not working at a time, but if i disable one LAN another is worked and vice versa.

To get a particular NIC to talk to a particular router you need to change the gateway address on the NIC to do so. You can force this by going into the TCPIP settings for each connection you have and assigning the appropriate gateway to it.

Actually the problem IS the two gateways.

Solution is take the gateway entry OFF the nic NOT connecting to the internet.

Given the setup there appears to be no reason for more than one router.
You should just connect everything via the switches and one nic.
