How do I select the NIC that is used for a multicast write?

[djalex]

The control PC has 2 NICs. Each are on seperate internal networks (192.168.xxx.xxx and 10.30.xxx.xxx). I want to send multicast data out the NIC attached to the 10.30.xxx.xxx networks. Currently the VI selects the NIC attached to the 192.168.xxx.xxx network. Does anyone know how I can force LV to select the desired NIC?

This is a Windows problem, not a LabVIEW one. Windows networking has to be configured to do what you want. This site helped me a little. Maybe someone with more networking experience can help.

Thanks for the pointer. The article lead me to the idea of setting up a static persistant route, which fixed my problem.
