I'm going to setup an additional Exchange 2000 server for OWA. I need some help about the installation

I have tried to install the server as a stand alone server but it was not possible to install Exchange 2k afterwards because the server couldn't see til Active Directory
Is it poosible to install w2k only as a stand alone server or do I have to install w2k in my domain
Off course I will not run DCPromo on it

Hope to get an answer
