I heard that more than one utility is available to defragment the Active Directory database. Is this true?

In Windows 2000, Microsoft included a version of an Exchange Server utility—esentutl.exe—that can defragment database files. At a command prompt, type the following command to defragment ntds.dit (the default name for the Active Directory—AD—database file):

ESENTUTL /D ntds.dit [options]
For a list of the command options, type
ESENTUTL /?
or
ESENTUTL /help
Usually, you use Ntdsutil to defragment your AD database; Ntdsutil is still the most supported version
