Introduction

With Primary Computers feature in Windows 8, administrators can limit the Folder Redirection and Roaming User Profiles technologies to be applied only to a set of primary computers for the users. This association of primary computers for a given user is established in a linked attribute in Active Directory called ms-DS-PrimaryComputer. Manipulating this list through the ADAC (Active Directory Administrative Console) can become error-prone, and cumbersome if administrators are doing it on a regular basis for more than a few users. The scripts below are intended to ease the process of establishing the primary computer relationship for users and even automate it for a large number of users.

Powershell Cmdlets

This release includes four powershell cmdlets and these are:
  1. Get-XADPrimaryComputer : Retrieves the list of primary computers for a user from Active Directory
  2. Get-XADPrimaryUser : Retrieves the list of primary users for a computer from Active Directory
  3. Add-XADPrimaryComputer : Adds a computer to the list of primary computers for a user in Active Directory
  4. Remove-XADPrimaryComputer : Removes a computer from the list of primary computers for a user in Active Directory

These cmdlets have been developed using all the Powershell best practices and they provide detailed help and examples.

Requirements

The Powershell cmdlets can be executed from computers running Windows® 7, Windows Server® 2008 R2, Windows® 8 and Windows Server® 2012. You will have to make sure that the Active Directory Powershell modules are installed properly by referring to the Installation section here
