I have a 2 node cluster running AD on Windows 2000 server. The servers need replacing so i'm think of going down to one server on a ESX platform to run the AD. I'm going to use a Windows 2003 Server instead of Windows 2000. Can I just join the windows 2003 server to the current domain to replicate the sysvol and users and policies etc or is this not the correct way to do it?
