Setting up dual NICs

I have a Dell Poweredge web server running windows advanced server 2000. It has dual nics and is a stand alone machine.  I want to set up the nics as failover so that it will run if a cable is unplugged or whatever.  How do i set this up?  Currently, i have just one nic in use.  I have 2 ip addresses available for the machine.  Thanks for your help.

I think you'll need network cards with drivers that support this function. I've used Compaq's which have a Teaming function which will provide failover or load balancing etc. I'm not aware of builtin OS support for this.

I know that you can cluster multiple servers together using Microsoft Network Load Balancing (NLB) - I would guess that you could run it with dual-NICs in the same server...

For example...
Card A has 10.1.1.2
Card B has 10.1.1.3
Virtual IP is 10.1.1.4

Configure DNS and the clients to talk to the virtual IP address - if one card fails, the other will pick up the slack...

NLB is an option in Win 2K AS

Just plug each nic into the switch and assign a different IP address to each one, add an entry into DNS for <www.webserver.com> (or what ever it is) and make it point to both Ip address. (setup an alias) http://support.microsoft.com/?kbid=168322 you may need to do tis in the reverse lookup zone.

Separate addresses on the NICs is OK, but I think the EtherChannel solution is better - the Compaq "Teaming" system is a version of this.  You need a NIC driver with support for EtherChannel - all the Dell Poweredge servers released in the last 2-3 years have this with the drivers on the Dell support site.

You configure the two (or more) cards with one shared IP address.  You then need to configure the switch you plug them into so it knows that they are part of an EtherChannel group (on Cisco IOS switches it's the "port group <n>" command).

In normal operation the switch and the NICs load balance the traffic, if one link fails the other takes all the traffic, no address changes, no disconnection, no DNS management, just a resilient experience....

I have not had good luck with teaming on Compaq, connecting to my group on Cisco...  maybe the Dell will be better?
What type of switch is this server connected to?
