To set up DNS for a child domain, create a delegation record on the parent DNS server for the child DNS server. Create a secondary zone on the child DNS server that transfers the parent zone from the parent DNS server. Note Windows Server 2003 has additional types of zones, such as Stub Zones and forest-level integrated Active Directory zones, that may be a better fit for your environment. Set the child domain controller to point to itself first. As soon as an additional domain controller is available, set the child domain controller to point to this domain controller in the child domain as its secondary.

Make sure that you have a good router, if you have it's good if you don't, get one (some routers show very poor performance when the number of users is more than 10). Then you have to specify what kind of server you want to have. If it's just a file server you don't need to do something extra. Just connect the server to the router create shared folders and so on. If you want to create a DHCP server you have to turn off the DHCP server inside of the router (if it has any). For a mail server you need some work extra and plus a domain controller. And so on.
