Re: Two networking cards

Ray,
What I think is happening is that your routers are routing all the traffic
between your subnets out through the internet and back in again. Unless you
have set up RIP or static routes on your workstations. Is that the case? Use
tracert to find out.
Network Teaming allows multiple network cards to share a single IP address
thus doubling or more your network bandwidth to the server. I don’t think
that's what you are after. Do you want to load balance the internet or local
network?
