I worked on a Windows based NAS Server which has 2 gigabit NICs and 2 10/100 Mbps NICs in it.
So what happens is that you can team two NICs into one.. following are the types of teaming that can be achived in this --
1. Load Balancing Mode
2. Fault Tolerance Mode
.. there are few more but i m not able to recall this as of now.
but incase you want details mail me on
