windows 200 network

I am trying to set up a small network in my house to practice using server 2000. I am starting from scratch so i am not upgrading my domain. I have one computer with 2000 server on it in a workgroup. This is the first computer how do i make this the PDC and create the domain. I cant upgrade the server from the workgroup because there is no domain to locate. What can i do to make this computer the first server in the network i want to create???? please help….
