    First, look on the microsoft knowledge base for multihomed servers. Second, multiple nics are ideal if you are looking to subnet your network an you want a NIC for each subnet which will "increase bandwidth" to the individual subnet. NT does not do load balancing across the NICS on its own if that is what you are looking for. But, check out the knowledge base, there are gobs (yes gobs) of information about configuring multihomed servers and many of the wonderful uses.

    Let's ask this question a little different. Why do you need two NIC's? At work we use three. One for the cluster link, and one for each of our two main switches, to provide some redundancy. At home I use two - one for my internal network, on for the internet - my NT server is set using DDNS and Proxy to allow my machines one shared IP and to allow me to setup a Web Server on DHCP using an auto host name.

    A company we contract for has a server, NT4.0, on a 100mb network. 15 employees, I would like to offer more output bandwith to the network, so I figure add another card, give it a adjacent IP address, bamo you have twice the bandwith???

    how network dependent are they? Other than just being a nice guy why else do you feel they need more bandwidth from the server? What do they use the network for? Programming? Database? Word docs? Graphics? Video Editing?

    Engineers, they have over 100gigs of acad drawings. There network is fast right now, but if several people are updating large drawings the network is noticably slower.
    Network consists of
    Dual PIII Server 700mhz
    512megs Ram
    100mb Intel Nic's everywhere

    100mb Baynetworks Switch
    All this Rackmount of course.

    Any chance of going Gigabit on the server and being able to add a gigabit port to their current switch setup?

    Cost is the big issue there, they do not see spending the $1000's to do that.

    Hmmmm......any chance of setting up 2 VLan's on that switch and then using cyberhh's technique of a NIC per LAN? Kinda grabbin at straws here. Lets look at what we can make the switch do, can you manage the switch? Can you assign each port for the client which server port to point to when looking for the server...
