I have an existing peer-to-peer network with machines running XP. I bought a Dell with Server 2003 loaded. The install instructions say to hook all the existing machines to the new server during configuration. But it recommends the server provide DHCP services. If I disable DHCP on the existing router, how will the client machines get an IP address before the server is up and functioning? Seems like a chicken and egg scenario.Related, I have DSL coming in to a linksys router. (Only one network port in the new server.) Do I need to keep the router between the DSL modem and my new gigabit switch, or will the server handle all the functions that the router now does (server has settings for PPPoE info)? Can the DSL modem connect directly to the switch? Do I need a cross-over cable to do this?
