|W2K server was a much better product for a server than xp would be.|
That is because Windows XP was never designed to be a Server OS. It is a client OS that connects to a server or a standalone OS in a peer to peer network.
The server OS comparable with Windows XP is Windows Server 2003.
All this assumes that the OP wants a server OS. If there is no requirement for a Server OS, and the OPs post suggests that, then Windows XP is a good choice.
