FineBuild can install and configure Windows Access Based Enumeration (ABE) as part of the SQL Server install process. If you do not want to include Access Based Enumeration in your FineBuild install, then do not download it.
Access Based Enumeration is written by Microsoft. It was chosen to be included in FineBuild because it prevents users who do not have access to the server from discovering information about shares and other details for the server. Access-based enumeration should be activated for all SQL Server machines.
Access-based enumeration was introduced as an optional component in Windows Server 2003 SP1 and can also be installed on Windows 2008. It is a standard part of Windows 2008 R2 and above, but it still needs to be configured.
