on a server 2000 machine with 2 NICs, is there a way to point internet explorer at a particular NIC?

Thanks. We'll let you know when a new response is added.

You can do it by specifying the default route to a particular interface from the command line, and then if you want the rest of the software on the system to use a different NIC, then specify local routes with a low metric to the other one.

Here’s the sample syntax:

Assume that you have two NICs on this machine with IP addresses respectively of 192.168.249.105 and 106.

route -p add 0.0.0.0 MASK 0.0.0.0 192.168.249.105 metric 10
route -p add 192.168.249.0 MASK 255.255.255.0 192.168.249.106 metric 5

The -p parameter makes the routes persistent until removed manually – meaning that they’ll survive a reboot.

HOWEVER – do not use the -p value until your testing shows that everything works.

Also – do not forget that the machine has static routes on it, or it WILL come back and bite you in the butt.

    Yes and NO. We have to guess why you have two NIC's in a 2000 Server, usually that is is for firewall, Internet connection sharing, or some sort of routing. If it is ICS (connection sharing) the system know that the Internet is on the adapter with a public IP address and only goes to the other if specifically pointed to a private address. The NO comes about if you are doing routing and the 2k system is acting as the bridge between two subnets. Then since both NIC's have public addresses IE will try both on the initial request and use the shortest path once that is established. It is also a NO if you doing load balancing with both NIC's using the same IP address. Hope this helps and Good luck.
