I've got a brand new Dell server with four network interface cards built in and its running Windows Small Business Server 2011. Its a small office with 10 desktop computer, basic configuration, one subnet and a single 192.168.10.1 - 192.168.10.254 IP address range. If I connect all four NICs to the network switch will it provide automatic redundancy for the network connection? Is there anything that I need to configure in order for it to work or is simply plugging them in enough? Is this even intended use of multiple nics?
