How To Decrypt many files in AD RMS When You Do Not Have Access to Them

Active Directory Right Management Service (AD RMS) is a security tool that you can deploy to your users that allow them to determine what kind of access users or groups have to the content that a user generates. A very good question from class is how do you decrypt the data if you need to get access to it when you were not given AD RMS rights. The answer is with the AD RMS Bulk Protection Tool. You can download it from here (http://www.microsoft.com/downloads/details.aspx?FamilyID=F9FBE58F-C175-41D0-AFDC-6F160AB809CD&displaylang=ru&displaylang=en)

Once you download the .msi file, double click it to allow it to install.

Click Install

Click Finish when the installation completes.

To start using the AD RMS Bulk Protection Tool:

Click Start / All Programs / AD RMS Bulk Protection Tool / AD RMS Bulk Protection Tool

A special command prompt windows will open. Give it a few seconds to finish loading. We need to know the location where the files are that need to be decrypted. The syntax for this operation is:

RMSBulk.exe /decrypt \\ServerName\ShareName

Be aware that I was able to decrypt documents using a standard user account that did not have any AD RMS access rights on the documents to begin with. This is a very powerful tool.

One more note, This has to be ran on a Windows Vista, Windows 7, or Windows Serer 2008 R2 machine.

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix.  This customization deals with Group Policy and PowerShell.  For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material.  I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO.  This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy.  One organization in the crowd had over 5,000 Group Policies.  In an environment like that, the comment section can be priceless.  I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2   #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique   # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers.  The first command creates a collection with 2 duplicates of both 1 and 2.   The second command creates another collection with the duplicates filtered out.  The Compare-Object cmdlet will first find items that are diffe
