DIT Explorer : A Comprehensive Tool For NTDS.dit File Analysis

DIT Explorer is a powerful Windows application designed to navigate and analyze the structure of NTDS.dit files, which are critical components of Active Directory databases.

Developed in C# using Visual Studio 2022, this tool provides an intuitive interface for researchers and administrators to explore the hierarchical structure of domain directories.

Key Features Of DIT Explorer

  • File Opening and Repair: Users can open NTDS.dit files directly from the application. If the file is unclean (e.g., pulled from a shadow copy), it may require repair using the esent /p command before opening.
  • Hierarchical View: The application displays the domain hierarchy on the left and the contents of selected nodes on the right. Users can double-click or right-click objects to view attributes, members, and groups.

  • Search Functionality: Users can search subtrees by right-clicking the root node and selecting Search Subtree. Searches can be filtered by object name or class.
  • Customization: The view can be customized by selecting which columns to display in the list views. This is done by right-clicking and choosing Columns…
