# AdRestore - Sysinternals | Microsoft Learn

Here’s a concise summary of the AdRestore article by Mark Russinovich (Nov 25, 2020):

* AdRestore is a simple command-line utility for Windows that enumerates deleted ("tombstoned") Active Directory objects in a domain and lets you restore them.
* It targets the tombstone restore functionality introduced with Windows Server 2003.
* The utility’s source code is based on sample code from the Microsoft Platform SDK.
* The article references Microsoft KB 840001 for guidance on restoring deleted user accounts and group memberships: <https://support.microsoft.com/kb/840001>
* A downloadable package is available: <https://download.sysinternals.com/files/ADRestore.zip> (512 KB).
* Additional related training is linked: Troubleshoot Active Directory - Training — <https://learn.microsoft.com/en-us/training/modules/troubleshoot-active-directory/?source=recommendations>

If you want, I can list the exact commands or provide step-by-step usage based on the tool (if that content is available).
