Installing ADSI Edit on Windows Server 2003

Posted on Updated on

Whether you are performing a schema extension or manually cleaning up metadata after a failed Domain Controller demotion, ADSI Edit is the tool you need. Because it interacts directly with the Active Directory database, it is powerful—and dangerous.

Warning: ADSI Edit does not have “undo” functionality. Always ensure you have a valid System State backup before making manual attribute changes.

Step 1: Locating the Installation Files

On Windows Server 2003, ADSI Edit is not installed by default. It is part of the Windows Support Tools package.

  • From the CD: Insert your Windows Server 2003 installation media and navigate to: [CD-DRIVE]:\SUPPORT\TOOLS\
  • Run the Installer: Double-click SUPTOOLS.MSI and follow the installation wizard.
  • No CD? You can download the “Windows Server 2003 Service Pack 2 Support Tools” directly from the Microsoft Download Center.

Step 2: Launching the Console

Once the Support Tools are installed, you can launch the editor:

  1. Go to Start > Run.
  2. Type adsiedit.msc and press Enter.

Step 3: Troubleshooting “adsiedit.msc not found”

If you have installed the tools but still receive an error that the file cannot be found, the system likely hasn’t registered the required library (.dll) file properly.

To manually register the DLL:

  1. Go to Start > Run.
  2. Type the following command: regsvr32 adsiedit.dll
  3. You should see a success message stating that the DllRegisterServer succeeded.

What can you do with ADSI Edit?

ADSI Edit allows you to view and edit the three primary partitions of the Active Directory database:

  • Domain Partition: Contains the users, groups, and OUs.
  • Configuration Partition: Contains forest-wide configuration data (like site topology).
  • Schema Partition: Contains the definitions for every object type and attribute in the forest.
