What happens to user names and permissions when you promote a server
I have a domain controller setup with 'businessname.corp' as the domain. Now I'm needing to setup a backup domain controller. The server however that will need to be a backup domain controller already has user names and complex file permissions. It's also functioning as a web server as well. What is going to happen if I promote this standard Windows 2003 server to a backup domain controller? Will the user names and file permissions stay intact or am i going to be starting from scratch?
