Bulk Password Reset – Active Directory

As Technet Gallery is retiring so moving the code to Git Hub. (click below github download link for this script)

Bulk Password Reset – Active Directory

I was contacted by our Active directory team as they wanted to reset the password of hundreds of users.

They need a powershell spell that can do below:

  • Read userids (samaccountname) from text file.
  • Reset the same password for all.
  • user must change password should be unchecked.

Sharing the script that has been quickly written to perform this magic.

 

You can download the script from below link.

Bulk Password Reset – Active Directory

Now create a text file, for example users.txt with all the samacountnames for which you want to reset the password.

 

Now open powershell and change to directory where you have placed the script.

Run the script, it will ask you for the password that you want to set and file that contains bulk users.

Script will create logs and report folder to place log and csv report of the whole bulk operation.
