Hello, right now we have a server in place (Server A) which is our primary Active Directory DC, our DHCP server and our DNS server, it also serves as our primary File Server running on Win 2000 Server ed. Server A is very low in disk space right now and therefore we decided to purchase Server B, which is newer and faster but comes with Windows 2003 Server ed. We want to setup Server B as the new Active Directory DC, DHCP server and DNS Server and leave the Server A only as a file server. I have an idea of how to do this in theory, but I have never really done it. I was wondering if someone could suggest some planning tips or direct me to some documentation on a planning strategy to take before doing this big change.
