Forcing windows IP beheviour

[Nowhere]

I have the following problem

I have a network interface on Windows2003 with two IPs.

I have an application on that server that uses IP IP_A, I want to force that same application to always use IP IP_B when connecting to a specific range/single IP.

I have tried to force routing like this

route add single_ip_I_want_to_force IP_B

Of course to no avail.

Could it have something to do with promiscous mode? Some NICs can't be run in promiscous mode.

If the server has two NICs your best bet is to setup NIC1 with one IP and NIC2 with the other. You can then install RRAS and force any IP to route over a specific IP. If you only have a single network connection/NIC, RRAS will still probably be the way to go...

Speaking of which, are the two IP on the same subnet, or different subnets?
