Deploy Primary Computers for Folder Redirection and Roaming User Profiles

Applies To: Windows 10, Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2

This topic describes how to enable primary computer support and designate primary computers for users. Doing so enables you to control which computers use Folder Redirection and Roaming User Profiles.

Important

When enabling primary computer support for Roaming User Profiles, always enable primary computer support for Folder Redirection as well. This keeps documents and other user files out of the user profiles, which helps profiles remain small and sign on times stay fast.

Prerequisites

Software requirements

Primary computer support has the following requirements:

The Active Directory Domain Services (AD DS) schema must be updated to include Windows Server 2012 schema additions (installing a Windows Server 2012 domain controller automatically updates the schema). For information about updating the AD DS schema, see What’s new for Adprep.exe? and Running Adprep.exe.
Client computers must run Windows 8.1, Windows 8, Windows Server 2012 R2, or Windows Server 2012.

Tip

Although primary computer support requires Folder Redirection and/or Roaming User Profiles, if you are deploying these technologies for the first time, it is best to set up primary computer support before enabling the GPOs that configure Folder Redirection and Roaming User Profiles. This prevents user data from being copied to non-primary computers before primary computer support is enabled. For configuration information, see Deploy Folder Redirection, Offline Files, and Roaming User Profiles and Deploy Roaming User Profiles.

Step 1: Designate primary computers for users

The first step in deploying primary computers support is designating the primary computers for each user. To do so, use Active Directory Administration Center to obtain the distinguished name of the relevant computers and then set the msDs-PrimaryComputer attribute.

Tip

To use Windows PowerShell to work with primary computers, see the blog post Digging a little deeper into Windows 8 Primary Computer.

To specify the primary computers for users

Open Server Manager on a computer with Active Directory Administration Tools installed.
On the Tools menu, click Active Directory Administration Center. Active Directory Administration Center appears.
Navigate to the Computers container in the appropriate domain.
Right-click a computer that you want to designate as a primary computer and then click Properties.
In the Navigation pane, click Extensions.
Click the Attribute Editor tab, scroll to distinguishedName, click View, right-click the value listed, click Copy, click OK, and then click Cancel.
Navigate to the Users container in the appropriate domain, right-click the user to which you want to assign the computer, and then click Properties.
In the Navigation pane, click Extensions.
Click the Attribute Editor tab, select msDs-PrimaryComputer and then click Edit. The Multi-valued String Editor dialog box appears.
Right-click the text box, click Paste, click Add, click OK, and then click OK again.

Step 2: Optionally enable primary computers for Folder Redirection in Group Policy

The next step is to optionally configure Group Policy to enable primary computer support for Folder Redirection. Doing so enables a user's folders to be redirected on computers designated as the user's primary computers, but not on any other computers. You can control primary computers for Folder Redirection on a per-computer basis, or a per-user basis.

To enable primary computers for Folder Redirection

In Group Policy Management, right-click the GPO you created when doing the initial configuration of Folder Redirection and/or Roaming User Profiles (for example, Folder Redirection Settings or Roaming User Profiles Settings), and then click Edit.
To enable primary computers support using computer-based Group Policy, navigate to Computer Configuration. For user-based Group Policy, navigate to User Configuration.
- Computer-based Group Policy applies primary computer processing to all computers to which the GPO applies, affecting all users of the computers.
- User-based Group Policy to applies primary computer processing to all user accounts to which the GPO applies, affecting all computers to which the users sign on.
Under Computer Configuration or User Configuration, navigate to Policies, then Administrative Templates, then System, then Folder Redirection.
Right-click Redirect folders on primary computers only, and then click Edit.
Click Enabled, and then click OK.

Step 3: Optionally enable primary computers for Roaming User Profiles in Group Policy

The next step is to optionally configure Group Policy to enable primary computer support for Roaming User Profiles. Doing so enables a user's profile to roam on computers designated as the user's primary computers, but not on any other computers.

To enable primary computers for Roaming User Profiles

Enable primary computer support for Folder Redirection, if you have not already.

This keeps documents and other user files out of the user profiles, which helps profiles remain small and sign on times stay fast.
In Group Policy Management, right-click the GPO you created (for example, Folder Redirection and Roaming User Profiles Settings), and then click Edit.
Navigate to Computer Configuration, then Policies, then Administrative Templates, then System, and then User Profiles.
Right-click Download roaming profiles on primary computers only, and then click Edit.
Click Enabled, and then click OK.

Step 4: Enable the GPO

Once you have completed configuring Folder Redirection and Roaming User Profiles, enable the GPO if you have not already. Doing so permits it to be applied to affected users and computers.

To enable the Folder Redirection and/or Roaming User Profiles GPOs

Open Group Policy Management
Right-click the GPOs that you created, and then click Link Enabled. A checkbox should appear next to the menu item.

Step 5: Test primary computer function

To test primary computer support, sign in to a primary computer, confirm that the folders and profiles are redirected, then sign in to a non-primary computer and confirm that the folders and profiles are not redirected.

To test primary computer functionality

Sign in to a designated primary computer with a user account for which you have enabled Folder Redirection and/or Roaming User Profiles.
If the user account has signed on to the computer previously, open a Windows PowerShell session or Command Prompt window as an administrator, type the following command and then sign off when prompted to ensure that the latest Group Policy settings are applied to the client computer:
```
Gpupdate /force
```
Open File Explorer.
Right-click a redirected folder (for example, the My Documents folder in the Documents library), and then click Properties.
Click the Location tab, and confirm that the path displays the file share you specified instead of a local path. To confirm that the user profile is roaming, open Control Panel, click System and Security, click System, click Advanced System Settings, click Settings in the User Profiles section and then look for Roaming in the Type column.
Sign in with the same user account to a computer that is not designated as the user’s primary computer.
Repeat steps 2-5, instead looking for local paths and a Local profile type.

Note

If folders were redirected on a computer before you enabled primary computer support, the folders will remain redirected unless the following setting is configured in each folder's folder redirection policy setting: Redirect the folder back to the local userprofile location when the policy is removed. Similarly, profiles that were previously roaming on a particular computer will show Roaming in the Type columns; however, the Status column will show Local.
