JSI Tip 3877. Is there an alternate method for defragmenting the Active Dirrectory?

The preferred method for defragmenting the Active Directory is to use the Ntdsutil tool.

The Exchange Server ESENTUTL tool defragments database files. Open a CMD prompt and type:

ESENTUTL /D ntds.dit \[options\].

Typing ESENTUTL /? returns:

    DESCRIPTION:  Performs off-line compaction of a database.
         SYNTAX:  ESENTUTL /d  \[options\]
     PARAMETERS:   - filename of database to compact
        OPTIONS:  zero or more of the following switches, separated by a space:
                  /l - location of log files (default: current directory)
                  /s - location of system files (eg. checkpoint file)
                             (default: current directory)
                  /b   - make backup copy under the specified name
                  /t   - set temp. database name (default: TEMPDFRG.EDB)
                  /p       - preserve temporary database (ie. don't instate)
                  /o       - suppress logo
          NOTES:  1) Before defragmentation begins, soft recovery is always
                     performed to ensure the database is in a consistent state.
                  2) If instating is disabled (ie. /p), the original database
                     is preserved uncompacted, and the temporary database will
                     contain the defragmented version of the database.
