Does the NT kernel support two NICS on the same IP Network... IE 1

Does the NT kernel support two NICS on the same IP Network... IE 192.168.12.1
& 192.168.12.2 with Mask of 192.168.25.255 and GW 192.168.12.254?

Kernel supports many things, but...

You don't need more than one logical interface for each segment/subnet
(physical adapters can be grouped if they support Teaming).

Thanks a lot for your reply, but we are looking for redundancy... Does
"Teaming" require external software?
Thanks again.

NIC Teaming was developed exactly for some fault-tolerance when two or more
physical NICs are grouped together into one logical interface. Not every NIC
manufacturer develops Teaming drivers but the major ones do.

We developed a "Fault Tolerant Ethernet" (FTE) driver for our products where
we use two NICs connected to the same network subnet via different switches.
We followed the Fieldbus Foundation High Speed Ethernet Redundancy
specification. Most teaming schemes only look at which port to send out
packets and our FTE keeps track of not only what port to send out on but
also which port on the receiving node to send to.

Yes, it does. However, the computer will use one NIC or the other,
but not both, to access the network. To control which one it uses,
assign a metric to the network connection for each NIC, giving a lower
value to the desired connection:

1. Open the Network Connections folder.
2. Right click the desired connection.
3. Click Properties | Internet Protocol (TCP/IP).
4. Click Properties | Advanced.
5. Un-check "Automatic metric".
6. Enter a number between 1 and 9999 for the "Interface metric".
