256986 Description of the Microsoft Windows Registry



SYMPTOMS
After you grant new access rights to a folder by using the Subinacl.exe utility and you view the Security permission, you may receive the following error message:

The permissions on  are incorrectly ordered, which may cause some entries to be ineffective. Click OK to continue and sort the permission correctly, or press CANCEL to reset the permissions.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

For example, you can run the subinacl /subkeyreg command to grant permission in the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Alerter /grant=everyone=F

When you view the Security permission on the Alerter service, you may receive the following error message:

The permissions on Alerter are incorrectly ordered, which may cause some entries to be ineffective. Click OK to continue and sort the permission correctly, or press CANCEL to reset the permissions.



CAUSE
This problem can occur because Windows 2000 has introduced a new inheritance model in which directly applied access control entries (ACEs) have precedence over inherited ACEs. The computer implements this precedence by placing directly applied ACEs ahead of inherited ACEs in a discretionary access control list (DACL). Earlier versions of Microsoft Windows NT did not distinguish between inherited and directly applied ACEs.

When you use Subinacl to set the permission to grant full permission, the ACE is put at the end of the access control list (ACL). Because the ACE is directly applied, when you view the permission in Registry Editor, you can receive an error message as the ACE must be placed ahead of the other inherited ACEs. Subinacl does not arrange the ACEs properly.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
