aclui.dll Error Fix Download

The Security Descriptor in Windows is the feature by which an object that uses the discretionary access control system tracks its security settings. To edit the security descriptor a programmer can use the aclui.dll module so that the Security Descriptor control flags can be manipulated.

The Security Descriptor contains the following flags: Owner SID, Group SID, DACL (Discretionary Access Control List), and SACL (System Access Control List).

Programmers cannot actually see the security descriptor in the registry because Windows does not document how it is physically stored for each type of object. For example the security settings for a file will be stored as metadata in the NTFS file system which is hidden from view.

What the aclui.dll file can do is to allow the programmer to read the metadata and trace the security descriptor so that he can edit or modify it.

Objects in Windows NT are protected with security descriptors. Programmers assign an Access Control List (DACL) contained in the security descriptor for each machine. It is in the DACL that user accounts are listed with an assigned access mask which is a collection of individual access rights.

By using the aclui.dll file the programmer can dynamically edit the entries in the DACL to modify user-assigned settings. To protect a Directory object an appropriate DACL must be inserted in the NT-Security-Descriptor attribute. The programmer can open DACL to access the entries (ACCESS_ALLOWED_ACEs). Each entry lists a user security identifier with an access mask assigned.

The aclui.dll file contains MAPI or DAPI calls that it uses to access the content of the NT-Security-Descriptor. DAPI calls are less preferred when retrieving and modifying security descriptor content due mainly to the low performance of the DAPIStart call. When implementing production code in the aclui.dll file the programmer can either cache a DAPI session at start up or use MAPI.

What is a DLL?

DLL (Dynamic Link Library) files contain computer code and resources that can be used by multiple programs at the same time. This uses less system memory and helps your computer system run more efficiently. DLL files give program developers the ability to reuse code to add features to several programs without the need to write new code for each program.

There are many programs that require DLL files to function properly so when one of them is damaged or missing it will cause program crashes and poor system performance.

Suggested fix if you are experiencing aclui.dll error messages:

DLL files are important parts of your operating system and many programs require them to function. When these files become damaged or are missing it causes poor system performance and system crashes. To fix these problems the user must replace the damaged file with a valid working version. If a working version cannot be found the user may perform a reinstallation of their operating system.
