We have a Windows 2000 Active Directory Server that we want to wipe and rebuild. How do we go about this? The domain has 3 other systems on it that only use this domain controller for authentication and DNS. The actual domain controller was running as an internet DNS server and non-microsoft mail server. I have moved the mail system to another machine. I want to migrate DNS off this box (pretty sure I know how to do this..) then rebuild it. Will I have problems when taking this system down, and then plugging in a replacement with the same IP address, system name and domain name? Any tips?
