|standard physical configuration|
Internet<>router/firewall<>switch<>server and pcs
Internet<>router/firewall is gateway - dhcp is off
server provides dhcp in the correct amount and subnet
So lets say gateway is 192.168.1.1 255.255.255.0
Server is at 192.168.1.10 255.255.255.0
Server provides dhcp to 192.168.11 to 25 which provides 14 hosts (pcs)
dhcp would provide these details
192.168.1.? ip address for the workstation
You load ms dns server on the server
You configure dhcp to do dynamic updates to dns
You configure dns forwarders to that of your isps dns servers.
This is a standard basic configuration.
Now to the server. You don't say what you are running for server or if you want to do Active Directory. Please answer.
