This applies to domain controllers. It is not applicable for other systems. Run "Regedit". Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters". Note the directory locations in the values for: Database log files path DSA Database file By default, they will be \Windows\NTDS. If the locations are different, run the following for each: Open "command prompt (Admin)". Navigate to the NTDS directory (\Windows\NTDS by default). Run "icacls *.*". If the permissions on each file are not as restrictive as the following, this is a finding: NT AUTHORITY\SYSTEM:(I)(F) BUILTIN\Administrators:(I)(F) (I) - permission inherited from parent container (F) - full access

Fix Text (F-82573r1181119_fix)

Maintain the permissions on NTDS database and log files as follows: NT AUTHORITY\SYSTEM:(I)(F) BUILTIN\Administrators:(I)(F) (I) - permission inherited from parent container (F) - full access
