As you know, Directory Service Restore Mode can work only when the machine is windows based Domain controller. But could you please tell me what is the clue or reason to keep this option in windows XP machine? when you will boot your XP PC in safe mode by F8 key then you can see this option as well.
Directory Service Restore Mode: This mode is valid only for Windows-based domain controllers. This mode performs a directory service repair.
Thanks in advance for any help.
