Man  it has been awhile since i looked at where to change the bind order.   I think it is in network properties under advanced or something.  I dont have a windows box in front of me to check.  your agent.config looks correct.  Can you ping the array SP's from that box?  if you cant, then it is probally your bind order.  you need to make the nic with the IP address on teh same subnet as the array the top of the list.
I have a iscsi ax4-5 with dual storage processors directly connected to a host. The iscsi traffic is on a 172.x.x.x subnet (dedicated nics to the ax4) and the managemet interface is on my lan subnet 10.x.x.x . When installing the navisphere agent software it is required to inform the software of the ip address of the managemement interface or of the iscsi interfaces?  Thanks  Marco
