I have this one domain controller on a Windows 2000 domain that was improperly removed from the domain (it was not demoted). Although the server is no longer active as a domain controller, Active Directory still contains all the domain controller information as if it still existed. I was wondering what would happen if I re-promote a new domain controller with the same name/IP address? Would the new domain controller now act as the old one as far as all the Active Directory information pointing to it or will the SID information, for example, be different making the new promotin to the old name obsolete?
If this will not resume the role as the old server, what's the best way to remove the existing information that is no longer valid?
If it does resume the older server's role, will there be any negetive side affects?
Any help here would be great. Thanks!
