Two Nics on Win 2k Server

I would like to know how I should set up two Nics on my servers.
Server 1
1st Nic is for network access for servers and clients to access this server.
2nd Nic use to monitor Network (Internet access)

Server 2
1st Nic is for network access for servers and clients to access this server.
2nd Nic for FTP and Web access (Intranet)

How should this be done.
