One of the main benefits of having all of your resource information in
Active Directory is that you can easily find the information that you're
seeking using the Find dialog box. When setting up objects in Active
Directory, I recommend you always enter as much information as possible
for the objects you're creating. The extra effort will pay off when your
users start doing searches for these objects. The more information
you enter, the more users can search to find the appropriate resource they
need.
Access-Based Enumeration
Access-Based Enumeration (ABE) is a feature included with Windows Server 2012/2012
R2. ABE allows your domain users to list only the files and folders to which they have
access when browsing content on the file server.
ABE helps eliminate domain users' issues that are caused by users connecting to file
servers and seeing large numbers of files and folders the user cannot connect. ABE allows
users only to see files and folders to which they have access.
Knowing that ABE is working on the Windows Server helps you set up your
permissions properly. If you need to give a user the ability to see files and folders that
they might not be able to change, you need to allow them at least to read or view the
directories. As an administrator, it's important that you understand that Access-Based
Enumeration is working on the server and what you need to do to get a user around it
when needed.
Configuring Offline Files
If you have been in this industry long enough, you have seen a major change in end-user
computers. Years ago, only a few select users had laptops. They were big and bulky, and
they weighed almost as much as today's desktop computers.
The pendulum has swung in the opposite direction. It probably seems like every one of
your end users now has a laptop. As an IT administrator, this gives you a whole new set
of challenges and problems to address.
One challenge that you have to address is how users can work on files while outside of
the office. If you have a user who wants to work at home, how do you give them the files
they need to get their work done?
The answer is offline folders . These folders contain data that can be worked on by users
while outside the office. An IT administrator can set up offline folders through the use of
Group Policy objects (GPOs) .
When you decide to make folders available for offline use, these folders need to
synchronize with the laptops so that all of the data matches between both systems. As
an administrator, one decision that you will need to make is when the offline folders will
