Through the years that I've spent supporting networks and their users, I've come across a common problem. I often have problems with having to give access to shared folders to users that also contain folders that they do not have access to. I'm of course the bad guy when I have to tell them that they do not have access to those folders. How dare I. Well, Windows Server 2008 (and Windows server 2003 SP 1with a plug in) offers a solution. It is called Access-Based Enumeration.
Access-Based Enumeration allows the operating system to filter out all the folders that the user does not have access to when the user browses to the shared folder. This helps to reduce user frustration, tech support calls, and increases user productivity by reducing the number of folders they see that do not apply to them.
So, how do you implement this magical wonder? Well, first off you need to have Distributed Files System installed and your distributed files configured. Next:
•Click Start --> Administrator Tools --> Share and Storage Management
•Open the properties for your distributed folder
•Click the Advanced button.
•Check Enable Access-based enumeration.
There is also a hotfix for Windows Server 2003 SP1 and Windows XP SP2 to be able to use DFS.
