It

That's why I said in the last post that it matters where you are located
when you try it. If you are pinging from machine in the same subnet as NIC2
then it will respond. If you are not, then "routing" must be enabled before
the NIC2 will communicate across subnets.

That doesn't matter.

That doesn't make any sense.

We are wasting our time here. You are getting this kind of behavior from the
machine because you have an over all bad design and are "covering" it with
bad techniques.

In the simplest form I can make it:...

Barring a few extreme and unusual situations, there are only two reasons to
put more that one nic in a machine:

1. It is being used as a NAT device or Proxy Server
2. It is being used as a LAN Router

In either case:
    A. RRAS must be running on the machine with "routing" enabled

    B. Only *one* Default Gateway exists.

    C. If there are "alternate" DFGs (for things like Dead Gateway
Detection) then they must be all in the same subnet and be assigned at the
same NIC as the normal Default Gateway.

    D. All other possible routes are handled by using Static Routes in the
Routing Table or by the use of Routing Protocols such as RIP, IGRP, etc.

    E. If the machine acting as a Router is in the center of a "hub & spoke"
design, operating as a single Router, then there is no need for any Static
Routes.
