Prior to ABE (Access-Based Enumeration), a user who had access to a share could see all the shares sub-folders, even if they didn't have permission to read the sub-folder.

If you enable ABE on a share, users who don't have permission to read a sub-folder will NOT be able to see the sub-folder when they enumerate the share.

NOTE: See Windows Server 2003 Access-based Enumeration tool. NOTE: If you have redirected user folders at \\ServerName\Users, you can hide the other user's folders by enabling ABE on the share:

         shrflags \\ServerName\Users /abe true /forreal

When I type shrflgs /?, I receive:

ShrFlgs V01.00.01cpp Joe Richards (joe@joeware.net) February 2005

Usage:
 ShrFlgs \\server\share \[switches\]

  server         Server to work with.
  share          Share name to work on. If '.' is specified, ShrFlgs
                 will enumerate all shares and display or update them.

  Switches: (designated by - or /)
   -forreal               Really make changes.
   -noadmin               Don't display admin shares.
   -abe (true|false)      Set/clear access-based enumeration.
   -afd (true|false)      Set/clear allowed forced delete.
   -nscache (true|false)  Set/clear Namespace caching.
   -exclopen (true|false) Set/clear allow exclusive open.
   -csc xxx               Set client side caching mode.
      Valid values for xxx:
        none   - No offline caching
        auto   - All files opened by user will be cached.
        manual - User selected files will be cached.
        vdo    - All files opened by user will be cached, optimized.


  Note: Access-based enumeration requires at least Windows 2003 SP1.
        You will not get an error on earlier OS'es if you try to set
         ABE, it simply will not be set.


  Ex1:
    shrflags \\server\sh1
      Display current settings for share sh1 on server
  Ex2:
    shrflags \\server\.
      Display current settings for all shares on server
  Ex3:
    shrflags \\server\sh1 /abe true /forreal
      Set access-based enumeration on share sh1 on server
  Ex4:
    shrflags \\server\. /abe true /forreal
      Set access-based enumeration on all disk shares on server
  Ex4:
    shrflags \\server\sh1 /abe false /forreal
      Set legacy enumeration on share sh1 on server
