load balancing between 2 DSL connections

Hi All,

I would like to make some changes to my business network and am not exactly sure how to start.

I have 2 DSL connections coming into our location. 1 serves 3 computers on a Peer2Peer 2000 network, the other serves 3 buildings/30 Win2000 computers in a client/server network.

I would like to bring the 3 computers in the Peer2Peer network into a seperate workgroup within the domain, and have all users share both DSL connections. All email and Websites are hosted elsewhere so that doesn't need to be considered.

I am just not sure the hardware/configuration needs of a solution like this and am hoping some of you could steer me in the right direction.

Thanks in advance for your help,
Jimmy
