Two Nics on Win 2k Server

Don't know what you really want to say here, but, you don't have to have 2 servers with 2 NICs each for accomplishing this.

You may have:
a) one server with one nick - let's say is the DC of the domain
b) one member server with two NICS - as router or NAT - you choose, so that you can connect to internet.

a)
IP address is from the private IP classes, with subnet mask and the gateway pointing to b) server (internal address too) - if u want that the DC access the internet, of course.
b)
First NIC - LAN IP private address
Second NIC - ISP IP address (to access Internet)
Install the RRAS service, start it and check either Router or NAT setup.
On the member server u can set up the ftp site and on the DC you can install Network monitor service and check the trafic on the LAN.

That's it in a very simple description.

Im with Vladolar in that you don't need 2 NICs on both servers. If your Server1 is a W2k/2003 server with AD, running as a DC with DHCP enabled AND say ISA server, then server2 can just be a member server for intranet FTP downloads. AD will control intranet users acces to shares on both server 1 and the member server2. ISA server [or similar firewall service] will control users access to the internet.
your comment that workstations have to have private address is moot using DHCP or even a static scheme with non routable addresses such as 192.XXX.XXX.XXX series.

Get a 4,8,16,24 port switch [depending upon how you want your workstations to connect to the LAN]. Connect the LAN NIC on server1 to the uplink port. The other NIC connects to your modem/router for internet access. The member server and worstations just needs to connect to a port on switch. This works is fine for small office environment or limited # of workstations.

All I want to know is how can I have server 1
Nic 1 have an IP of 192.168.1.X this is the one that network connections are made.
Nic 2 All I want to do is to be able to run a packet sniffer or other network monitoring programs on this. I want it to be able to resolve names from DNS.

Server 2
Nic 1 have an IP of 192.168.1.X this is the one that network connections are made.
Nic 2 I want to set as the access point for our users to FTP files from and access an Intranet on.
All of this is done behing the firewall.
Do I just set the network Metric differently?

I am not sure if I explained what I am attempting to do.
One server has nic2 connected to a cisco high speed hub and nic1 to a switch. The connection to the hub is for packet monitoring as our internet connection is also run through the Hub-I was told to come up with a way to check on users web access this set up works great for that but I don't want any traffic going out nic2 or I dont want any DNS to resolve to it. What is the best way to accoplish that?
On the second server I was thinking that I could have all of the Intranet-FTP traffic using nic1 and nic 2 used for server comunications.
