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

A. 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.
