How to Restore Active Server database from an old windows 2003 server installation to a new installation

Last Modified: 2008-05-30
We have a new installation of Windows 2003 Server on the same machine as a previous 2003 server. I reinstalled after working many hours with no luck on restoring a corrupt registry (no backup...). Now I have a newly built Server but all old users and file permissions are gone of course.
I still have the old NTDS directory with it's database. Is there a way to restore the old database over the current one?
I tried using ESENTUTL but this returned a checksum error. I may be doing something wrong but I ran the following from the old ntds path:
ESENTUTL /d ntds.dit

If you already have another DC in the domain up and running... just join this server to the domain and it will get all of its AD info during replication.

The Active Directory Restore Mode only applies to Win2K domain controllers. Let’s say you’ve deleted certain objects in AD that you need to restore from last night’s backup. You can use the AD Restore Mode to restore a user account, group, OU or other objects. Before you can restore objects in AD, you must have a System State backup—created through the Backup program—available that contains the objects you intend to restore. To access the Directory Service Restore Mode, press F8 when prompted during system startup.
