Two NICs with identical gateway metric

Windows Vista Business with SP1

I have two NICs in my Vista Business SP1 machine - one NIC is
connected to our corporate network, the other NIC is connected to a
private network. Both networks are using DHCP, with the private
network obtaining it's address from a LinkSys WRT54G (not being used
as a router - just a switch with DHCP).

The problem I having is that both networks end up with a entry in the
routing table for 0.0.0.0 with the same metric. So anytime I try to
access the internet (which should always go through the corporate
network), I have a 50-50 chance of actually succeeding.

How can I keep this from happening?

Thanks....

As a user of Vista for precisely 11 hours, I suggest you go to the
properties of the NIC on the private network and tell Vista this is a private
network. If this works it saves no end of complex interventions - but this
is purely amateur advice!

Hi
From pure network perspective , the whole setting is questionable.
I would drag an Icon from the Network connectors to the Desktop and right
click and disable the connector that you do not want to use at the moment.
It take 10 sec. to do so and you have less headaches.

Set a metric for the NICs and/or routes as appropriate for your needs.
Vista can't magically guess which direction traffic should go, routing
tables and metrics exist for a reason, use them.
