Changing the Binding Order of network interfaces does not affect routing
decesions

I have a computer with two network interfaces. The main one, which leads
to our main network, and a secondary one, which leads to its own little
network. When both are enabled, the traffic intended for the main network
wanders off into the secondary card and is lost. I tried changing the
binding order on the interfaces, but this did not help.
