I am getting ready to upgrade our 4.0 network to 2000. We purchased a new server and installed 2000 Server on it. As I was configuring it to be a DC, I specified that I wanted it to be a member of our current 4.0 domain. I received the error message: Domain xyz is not an Active Directoy domain or an Active Direcory domain controller could not be found. This leads me to believe that I need to upgrade my PDC first. Is that correct or do I want to "create a domain"?
