We had to switches install for redundancy within our Datacenter...if one goes down, the other is there to keep the network up and running. I want the servers to be dual NIC (done physically), so that if a switch goes down the other NIC simply takes up the load with no intervention from the User or Administrator...How do I setup the NICs to go to separate switches?? Some says clustering(I thought this was strickly for server clustering)...someone else said IP forwarding??? I'm lost...but I need redundancy........

You need to "team" the NIC's on the server so the two NIC's appear to the network as one interface.  A virtual NIC is created on the server and is configured for the TCP/IP information.  Plug one NIC into one switch and the other NIC into the second switch.  HP/Compaq NIC's support teaming and Windows 2000 Advanced server can do this using NLB (Network Load Balancing).  I'm sure there is other software out there to do this as well.

Agreed.  This is a hardware feature.  Your average desktop PC will not be able to do this, but your average server PC WILL.
