Have 2 NICs on Windows 7 Pro System - would like to connect both to separate subnets and have them accessible from each.

We have a network video recorder that is receiving video from 24 IP based cameras which are on a separate subnet (192.168.0.x). The main network (which has the internet) is on (192.168.1.x). We would like to make it so the 192.168.1.x network is the primary (which I thought could be done using metric values) and have the cameras on the other subnet (192.168.0.x) accessible. This was working, however the network video recorder has been going offline.

Is there a resource available that will guide us on the best way to accomplish this task?

What exactly do you mean with metric values? So the video recorder is hanging on the Windows 7 system or is the Windows 7 system the recorder?

How are the NICs configured exactly? Just the one gateway (which it should have)?
Poly11Author Commented:
NIC is configured on the subnet that has the internet connection. Below are the addresses:

NIC 1: (internet connection)
DNS: (service provider)

NIC2: (camera network)
Gateway: nothing entered
DNS: nothing entered

The problem is that the NVR goes off of the internet and eventually reconnects. We have replaced the wires, router and switch but still have the same issue. We have even switched the NICs and still have the same problem. The metic value I referred to is under the advanced configuration settings for IPV4.

Wouldn't this need routing to work optimally? Maybe I'm missing something, it's getting late here :)

You could try by adding a route to your routing table on the Windows system

Something like route add MASK
That would let the two networks kind of talk with each other ...

The "metric" in this case is the "cost" a of particular route off the network.  If there's more than one way off, you can use the metric to give one route preference.

Try this:
Bring up the Network Connections (Control Panel\Network and Internet\Network Connections) window
Press ALT, then select Advanced -> Advanced Settings...
In the upper half of the Advanced Settings dialog, change the order of the connections so that NIC2 (the DVR network) is above NIC1 (the internal network).
