    The problem is that you have a gateway set for each.  I've run into this issue when multi-homing servers in the past.

    depending on what you are trying to achieve, the multihoming will be a problem. Windows 7 is capable of utilizing two different networks at the same time, but you have to be able to differentiate them somehow.

    The computer has two DNS setting and has no way to determine which you want to reference when a DNS request comes in.

    As for "browsing", as in the computer network, this will be a problem.

    You can set a priority to the routes manually, but I will bet you still have issues.

    currently i disable one of the nics and access systems and intranet / internet - then when i need to access the other side i enable the other nic. just cant do it at the same time. it would be helpful to configure or hard code a specific intranet site out a specific interface..

    you can setup hard coded entries in you hosts. file in the C:\Windows\System32\Drivers\etc folder.

    Enter the information for a specific site name with its IP address.

    Example:              #Intranet site 1          #Intranet site 2

    You can have both enabled at the same time if you remove the gateway from one of the NICs.  If you remove the gateway from the test NIC you would be able to get to resources on the test subnet ( but all Internet traffic would flow out the production NIC.  If you are just trying to get to the test Intranet at then this should work for you.
