The NT File Replication Service database is located at %SystemRoot%\Ntfrs\Jet\Ntfrs.jdb and the logs are in the \Log subfolder at %SystemRoot%\Ntfrs\Jet\Log.

If you wish to relocate these objects:

1. Type net stop ntfrs at a CMD prompt.

2. Use Regedt32 to navigate to:

    HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\NtFrs\Parameters

3. Double-click the Working Directory value name in the right hand pane and change the path in this REG_EXPAND_SZ data type
    to reflect the new path. The default is %SystemRoot%\Ntfrs.

4. Type net start ntfrs at a CMD prompt.

When the service starts, it creates a new folder tree with the Administrator and System account having Full Control:

\Ntfrs
\Ntfrs\Jet
\Ntfrs\Jet\Log
\Ntfrs\Jet\Sys
\Ntfrs\Jet\Temp
