On a Windows XP-based computer, you cannot access subfolders and files in a share folder in Windows Explorer if Access-based Enumeration is enabled for the share folder

Support for Windows XP has ended

Microsoft ended support for Windows XP on April 8, 2014. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Consider the following scenario.
  • On Windows Server 2003-based computer, you create a share folder.
  • In this share folder, you create some subfolders and files.
  • You deny all users the List Folder/Read Data permission to this share folder.
  • You enable Access-based Enumeration for this share folder.
When a user tries to access the subfolders or the files in the share folder from a Windows XP-based computer, the user enters the Universal Naming Convention (UNC) paths of the subfolders or the files in the Address bar of Windows Explorer. In this situation, the user receives an error message that resembles one of the following error messages:
  • The path for the folder cannot be found.
  • Access is denied.
  • This problem will not occur if the user accesses the subfolders or the files at a command prompt.
  • This problem will not occur if you disable Access-based Enumeration for the share folder.
This problem occurs because of an error in the Shell32.dll file.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Access-based Enumeration is a new feature that is included in Windows Server 2003 Service Pack 1. This feature lets users of Windows Server 2003–based file servers to list only the files and folders to which they have access when they browse content on the file server. This eliminates the confusion that may occur when users connect to a file server, and then they encounter lots of files and folders that they cannot access.
