When you are forced to do an emergency repair on a Windows server and there is no Emergency Repair disk, or the Emergency Repair disk was created before an eDirectory installation, the eDirectory client is removed and Registry settings are deleted. The nds4nter.exe utility both restores the necessary Registry settings and reloads eDirectory files.
Run nds4nter.exe from the \i386\goodies directory.
After an emergency repair is performed, run the Emergency Repair utility from the CD. The utility will first restore some of the Registry settings, then it will launch the eDirectory installation. The installation will copy the files then you must select the reboot option. After rebooting, users will have access to the migrated domains.
