There are some situations where you need to promote your Windows Server to domain controller and to demote domain controller to member server. This is possible using the Dcpromo.exe (Active Directory Installation Wizard) feature of Microsoft Windows Server. This wizard deletes configuration data for domain controller for the Active Directory, as a part of demotion process.
It takes form of the NTDS settings object, which is stored as child of server object in the Active Directory Sites and Services. However, if you use the Dcpromo.exe utility incorrectly, you may come across serious problems of system failure and data loss, which ultimately requires hard drive recovery to be fixed.
The information about promotion process and NTDS settings is stored in Active Directory in the below location:
Attributes of NTDS settings object has data that represents how domain controller is recognized by the replication partners, naming contexts which are organized on machine, default query policy, and whether domain controller is global catalog server.
If NTDS settings objects are removed improperly, Exchange Server administrator can manually delete metadata for server object. Administrator can manually delete NTDS Settings objects in Windows 2003 Server and Windows 2000 Server using Ntdsutil.exe tool. Before you modify the Active Directory attributes or remove server objects, you should keep the following things in mind:
When you use the LDP utility, ADSI (Active Directory Service Interfaces) Edit snap-in, or any other LDAP (Lightweight Directory Access Protocol) client version 3 and you improperly modify the Active Directory object attributes, you may come across serious problems. Such problems may cause operating system malfunction and require you to format the hard drive and reinstall operating system.
You should always make sure that you have complete backup of your mission-critical data after demotion before you manually remove NTDS Settings objects from any server. Incorrect use of Ntdsutil.exe utility might affect Active Directory and cause severe data loss situations.
When any of the above problems occur and you face serious data loss from your Windows hard drive, windows hard drive recovery is the best option to sort it out. The hard drive recovery is possible using third-party data recovery software.
The hard drive data recovery applications use high-end scanning techniques to carry out in-depth scan of entire hard drive and extract all lost data from it. The have interactive user interface and read-only conduct to ensure easy and safe recovery.
Stellar Phoenix Windows Data Recovery is the most efficient and advanced utility that recovers lost data in all scenarios. The software is compatible with Microsoft Windows 7, Vista, 2003, XP, and 2000. It recovers data from all FAT12, FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions.
