As the subject says. I recently brought W2K server but due to compatabilty problems with existing structure. I now need to install W2K Server(which you can't buy anymore). Now I know that the W2K3 server licence covers me for W2K but what product key do I use? The W2K3 key doesn't work and the W2K server software I have is a copy with no key. I also don't really want to use a hacked/cracked/illegal key.
