I have assigned all three NICs IP addresses that are outside the DHCP pool. I have 2 NICs are connected to 1 switch and the 3rd to my second switch.

I want to assign one of the two NICs on the 1st switch to "normal" network activity (e.g. internet access, RDP, etc.)

The other two NICs I want to reserve for mirroring ports on their respective switches.

While this machine is connected to the domain I can access the internet and Remote Desktop. I have no idea which NIC I am using until I start mirroring a port, at which time, if I happen to be connected through one of the NICs I have dedicated to mirroring, I lose my remote desktop.

I am aware that I would have more control over the NICs using Linux. I want to explore Windows solutions before I go that route because reinstalling another OS would be inconvenient (but not impossible). I would likely use a version of Backtrack (3 or 4 not sure). I would also have to learn how to access the machine remotely but I've done it before so this would be a minor obstacle.

Thank you for your assistance.
