Best way to setup Bloomberg Multi Homed (2 Network Cards, 1 switch, 2 routers) machines

I have a scenario where my users are all working on Bloomberg PC terminals with 2 NICs. One NIC is for the LAN, and the other is specifically for Bloomberg network traffic (There are two routers: 1 bloomberg and one regular internet T1 plugged into one common switch). These PCs will serve as regular network workstations, all participating on a windows domain as computers. They will be accessing LAN resources and the internet from the LAN NIC card configured with DHCP, and retrieving their internet and IP settings from the T1 Router. The Bloomberg NIC will be used ONLY when the bloomberg software is running and will route traffic through Bloomberg's private IP network (non internet).

I setup everyone with static routes to the BLoomberg Network (10.39.208.x) which will talk directly to the LAN side of the Bloomberg Router. On the LAN Nic, the DHCP address is 10.10.10.x.

Sometimes, everything works great, but others they can't go online or access the domain controller until i disable the Bloomberg NIC. Am i doing something wrong here? Do i need to employ a router to manage these multi-homed PCs?
