I have to reset multiple accounts passwords. I's looking for a way to use the powershell to read csv file and then update the password just like I did before (http://iambusychangingtheworld.blogspot.com/2013/08/activedirectory-update-user-info-from.html). Unfortunately, the Active Directory Module for Windows PowerShell is only available in Windows Server 2008 R2 and Windows 7 which I don't have now (only Server 2008 SP2). So, I's googling around and then I found this:
Bulk Password Control
This free tool can help me update all the users passwords which are auto generated. It even let me export the information to csv file. It's so cool!
Note: install this tool inside the Active Directory Domain Controller.
