We have only one domain server. It is NT4. We have purchased a new server with Windows server 2003 on it. It is working on our domain. We be retiring the NT4 box very soon. As a start to this process, can i promote the Windows 2003 server to be a domain server while the NT 4 box is still our Primary Domain Server? If not, how do i get the 2003 server to be a domain server? Any help would be greatly appreciated.
