Is it possible to have 2 network cards in 2 different PC's and use them both with load balancing for the same connection?
What I wanted is to get close to 200Mbps in a 100Mbps switched LAN for windows file sharing (so using only one connection).
Is this possible? And if so, what configurations I need to do?
You can do it, but the NIC's have to be able to load-balance and have drivers to provide this. And you need a switch which can be configured to support it. But why bother when you can set up a 1Gb LAN with single interfaces.

Humans become confused when presented with too many choices, and will limit themselves only to an inefficient subset of the available choices or none at all.
A 100Mbit switch capable of load-balancing interfaces is more expensive than a 1Gbit switch. Unless you have a reason for load-balancing such as redundancy the 1Gbit solution is usually cheaper.
