Facilitates managing Active Directory Lightweight Directory Services (AD LDS) application partitions, managing and controlling flexible single master operations (FSMO), and cleaning up metadata that is left behind by abandoned Active Directory domain controllers and AD LDS instances. (Abandoned domain controllers and AD LDS instances are those that are removed from the network without being uninstalled.)

Dsmgmt 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 dsmgmt, you must run the dsmgmt 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 dsmgmt 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 manage configurable settings:

configurable settings
co s

The short form for each command is listed in the following table.
