Performs database maintenance of the Active Directory Domain Services (AD DS) store, facilitates configuration of Active Directory Lightweight Directory Services (AD LDS) communication ports, and views AD LDS instances that are installed on a computer.

Dsdbutil is a command-line tool that is built into Windows Server 2008. It is available if you have the AD LDS server role installed. To use dsdbutil, you must run the dsdbutil command from an elevated command prompt. To open an elevated command prompt, click Start, right-click Command Prompt, and then click Run as administrator.

For most of the Dsdbutil commands, you only need to type the first few characters of the command name instead than the entire command. For example, you can type either of the following commands to activate an AD LDS instance named instance1:

activate instance instance1
ac i instance1
