Compact the database file to a local directory or remote shared folder, as follows:
1. Open a Command Prompt as an administrator.
2. At the command prompt, type the following command, and then press ENTER: net stop
ntds
3. Type Y to agree to stop additional services, and then press ENTER.
4. At the command prompt, type ntdsutil, and then press ENTER.
5. At the ntdsutil prompt, type activate instance ntds, and then press ENTER.
6. At the ntdsutil prompt, type files, and then press ENTER.
7. If you are compacting the database to a local drive, at the file maintenance: prompt, type
compact to <drive>:\ <LocalDirectoryPath> (where <drive>:\ <LocalDirectoryPath> is the
path to a location on the local computer), and then press ENTER.
8. If defragmentation completes successfully, type quit, and then press ENTER to quit the
file maintenance: prompt. Type quit again, and then press ENTER to quit Ntdsutil.exe.

Note
You should make a copy of the existing Ntds.dit file if at all possible, even if you have to
store that copy on a secured network drive. If the compaction of the database does not work
properly, you can then easily restore the database by copying it back to the original location.
Do not delete the copy of the Ntds.dit file until you have at least verified that the domain
controller starts properly. If space allows, you can rename the original Ntds.dit file to
preserve it. Avoid overwriting the original Ntds.dit file.
9. Manually copy the compacted database file to the original location, as follows: copy
“<temporaryDrive>:\ntds.dit” “<originalDrive>:\<pathToOriginalDatabaseFile>
\ntds.dit”Ntdsutil provides the correct paths to the temporary and original locations of the Ntds.dit file.
