Windows File Share not using Correct NIC Interface.

Hi

I have Windows 2012 R2 server with two 1gb NICs.  I want to use NIC1 for the regular network traffic/Internet and the NIC2 for database traffic.  NIC1 has IP Addresses of 64.141.xxx.xxx (I am not showing the last 6 digits for security reasons) and 192.168.10.21.  NIC2 has the IP Address of 192.168.11.2.

The Workstation accessing this server also has two NICS.  NIC1 has the IP address of 64.141.xxx.xxx and 192.168.10.22.  NIC2 has the IP Address of 192.168.11.4.

I created a share on the server myDataShare$.  On the Workstation I access the share using \\192.168.11.2\myDataShare$ and everything works accept that the data from the share is sent across NIC1 but I want it to go over NIC2.  If I add static routes to both machines it makes no difference all network traffic always goes out on NIC1 for both machines.

If look at the status of each NIC on the send and receive bytes only NIC1 show any traffic.  NIC2 is silent.  How do I get traffic for the 192.168.11.0/24 subnet to use NIC2?

The strange thing is that if I ping a 192.168.11.0/24 address it goes over NIC2 but file sharing seems to ignore NIC2 altogether.

Thanks,

Simon
