MS initiator doesn't support teaming.
With 2 NICS, two switches and 2 ports on the SAN target you should go to the iSCSI initiator and login to all 4 paths to the LUN, then you can select Round Robin under load balancing policy, it doesn't always loa balance very well though as it's relying on equal traffic on each LUN,

There may be a DSM from Cybernetics, if not the MS DSM ought to work OK, don't forget to enable MPIO or you may see the same LUN 4 times.
