2 Default Gateways - How does it decide which to use?

don't use it,
add static routes instead
add route -p destination_subnet MASK destination_subnet_mask gateway_address
-> you can create as many static routes as you want, each pointing to a gateway address ---------------------------------------------------------------------
I have not failed, I've just found 10,000 ways that don't work

HI!
If you describe in details your design and configuration, it will be much easier to answer.
Anyway, AFAIK, NT uses the first defined router as default, and the other routers in these events:
* The default router is not available (I don't know the timeouts now).
* The client sends a packet to an address, that the router knows it is better to use the other router.
(The router should know about the other one using preconfigured static routes and/or routing protocol).
Then the router sends to the client an ICMP redirect message pointing to the other router.
The NT client updates its routing protocol, and now uses the other router for the rest of comunication to the same target network/host.
This update normaly stays until you restart the NT machine.
You can see the new route using the command
ROUTE PRINT
Note: This can happen even if the client is not configured with the second router IP address, since it is dynamicly learned from the default gateway.
In general, use the
ROUTE PRINT
command to debug and learn what happens.
Consult a routing expert if you have problems.
