Lets say we have a machine running critical business applications connected to the enterprise network on 2 NICs. From 
an assessment/audit point of view, is it necessary to scan both NICs using assessment tools like NMap and Nessus? 
Will both scan results produce the same findings (as in same ports and services open)?
Does the OS or applications influence the detection of ports/services on different NICs on the same physical machine?

Yes, you will need to scan each NIC and address the server is known as
just to make sure you have covered all the bases.

Services can be bound to a particular IP, and I frequent see
multi-homed machines (servers with more then one IP) having different
services available on the different addresses. The only reason I know
that they are the same machine is because if they use a single NIC the
MAC address is the same for both IPs, and of course when I gained
access to them the 'hostname' and 'hostid' reflect the same
information.
