How do I move win2003 from an old server to a new one and keep the name

How do I move win2003 from an old server to a new one

I manage the network and servers for a litle compagny. I am planning to move the main server (winsrvr2003 with DHCP, AD, DNS, Filesharing, RIS) from an outdated hardware to a brand new server.
I would like to keep the server’s name. T.U. guys. Please could you give me a link?
