multiple network cards

RUTAJEB

Suppose you have win2k box with 2 network cards. Dhcp on linksys router
supplies both nics with proper addresses.

When i initiate a tcpip connection(i.e. a http request)...

1. which NIC is being used for the communication?

2. How does windows decide which one to use; is there a way to specify
which one to use?

any ideas? answers?

thanks

Yes, you can do a route print and verify the default routes, to see
this. Both of ur cards will have an default route (0.0.0.0 0.0.0.0
gateway interface/ip metric) for each one. Now the one which has an
lower metric(say 1) will be used to send the traffic. If both of them
are of the same metric, then you will see that the tcp/ip stack might
have selecte one of them as the default gateway. You can see it, when
you print the routes. This default gateway will be used to send the
traffic. But, there are some algorithms, say dead gateway alogrithm
which will change the default gateway
