So why
defrag it in the first place?
One reason
you might want to defrag your NTDS.DIT
file is to save space, for example if
you deleted a large number of records at
one time.
To create
a new, smaller NTDS.DIT file and to
enable offline defragmentation, perform
the following steps:
-
Back
up Active Directory (AD).
-
Reboot
the server, select the OS option,
and press F8 for advanced options.
-
Select
the Directory Services Restore Mode
option, and press Enter. Press
-
Enter
again to start the OS.
-
W2K
will start in safe mode, with no DS
running.
-
Use
the local SAM’s administrator
account and password to log on.
-
You’ll
see a dialog box that says you’re in
safe mode. Click OK.
-
From
the Start menu, select Run and type
cmd.exe
-
In the
command window, you’ll see the
following text. (Enter the commands
in bold.)
C:\> ntdsutil
ntdsutil: files
file maintenance:info
....
file maintenance:compact to
c:\temp
-
You’ll
see the defragmentation process. If
the process was successful, enter
quit to return to the command
prompt.
-
Then,
replace the old NTDS.DIT file with
the new, compressed version. (Enter
the commands in bold.)
C:\> copy c:\temp\ntds.dit
%systemroot%\ntds\ntds.dit
-
Restart the computer, and boot as
normal.
