Understanding Item-Level Targeting Restrictions
Group Policy Preferences (GPP), including Drive Maps, offer granular control through Item-Level Targeting (ILT). This feature allows administrators to apply specific preferences based on security groups, operating system versions, hardware characteristics, or user attributes. However, ILT is strictly bound by the scope of the Group Policy Object itself. When you attempt to configure a Drive Map under User Configuration, the system checks the context in which the GPO is being edited.
If the GPO is currently linked exclusively to a Computer OU, or if you are accessing it via a tool that does not recognize a user context, the interface disables the ability to add user-based filters. This is a protective measure to prevent configuration errors where user preferences might inadvertently apply to computer contexts or vice versa. The grayed-out state indicates that the current editing environment does not support the requested targeting criteria.
Verifying GPO Link Scope
The most common cause for this issue is a mismatch between the GPO link location and the configuration section you are trying to edit. You must verify that the GPO containing your Drive Map preference is actually linked to an Organizational Unit that contains user accounts. Open the Group Policy Management Console (GPMC) and navigate to the domain structure.
- Locate the Organizational Unit (OU) where your target users reside.
- Check the GPO Links column to confirm the presence of the relevant GPO.
- If no GPOs are linked, create a new GPO or link an existing one to this OU.
It is crucial to remember that User Configuration settings only process when the GPO is linked to an OU containing users. If you have linked the GPO to a Computer OU instead, the user-side settings will not be processed during logon, and the targeting options may appear unavailable or ineffective depending on how you are attempting to edit them.
Checking Active Directory Structure
Ensure that the OU you are targeting is not a built-in container like Users or Computers. While these containers hold objects, best practices dictate creating custom OUs for grouping. If you are trying to target users in the default Users container, you may encounter permission issues or unexpected behavior. Create a dedicated OU for your target group and move the user accounts there. Then, link your GPO to this new OU.
Editing Permissions and Security Filtering
Even if the GPO is correctly linked, you might face restrictions due to security filtering. By default, a new GPO has "Authenticated Users" in its Security Filtering tab. However, if you have modified this list, ensure that the account you are using to edit the GPO has Full Control permissions on the object.
Additionally, check the Delegation tab in GPMC. If you are part of a restricted admin group, you might lack the permission to modify Item-Level Targeting settings. Navigate to the GPO properties, go to the Delegation tab, and click Advanced. Ensure your user account or group has Edit settings, delete, and modify permissions. Without these rights, the interface may lock down certain features, including the ability to set targets.
Resolving the Grayed-Out Interface
To fix the immediate issue of the grayed-out Users section, follow these steps:
- Open GPMC: Launch the Group Policy Management Console on a domain controller or a workstation with RSAT installed.
- Edit the GPO: Right-click the GPO linked to the user OU and select Edit.
- Navigate to Preferences: Go to User Configuration > Preferences > Windows Settings > Drive Maps.
- Create New Mapping: Right-click in the empty space and select New > Mapped Drive.
- Access Targeting: Click the Targeting tab at the top of the dialog box. If the GPO is correctly linked to a user OU, the options here should now be active.
If the tabs are still grayed out after confirming the link, try unlinking and relinking the GPO. Sometimes, caching issues in the GPMC client can cause UI elements to freeze. Refresh the console by pressing F5 before attempting to edit again.
Common Pitfalls and Best Practices
When working with Drive Maps and Item-Level Targeting, avoid using broad security groups unless necessary. Overly permissive targeting can lead to conflicts where multiple GPOs attempt to map the same drive letter. Use specific security groups for each mapping requirement. Also, ensure that the path specified in the Drive Map is accessible by all targeted users. If the UNC path relies on credentials that are not passed through, the mapping will fail silently, even if the targeting is correct.
For more complex scenarios involving standalone stations or specific denial rules, refer to our guide on Denying GPO Application to Specific User Account on Machine to understand how precedence and filtering interact. Additionally, understanding how GPOs apply to different station types can help troubleshoot why some settings do not appear as expected, as detailed in Applying GPO to Standalone Stations: A Step-by-Step Guide.
Frequently Asked Questions
Why is the Targeting tab grayed out for Computer Configuration?
The Targeting tab is grayed out in Computer Configuration if the GPO is not linked to a Computer OU or if you are editing it in a context that does not recognize computer objects. Ensure you are working within the Computer Configuration section of a GPO linked to a valid computer container.
Can I use Item-Level Targeting with Local Group Policy?
No, Item-Level Targeting is not available in Local Group Policy (gpedit.msc). It requires a Domain Controller and a properly linked GPO within Active Directory. You must use the Group Policy Management Console (GPMC) to configure these settings.
What happens if I target a non-existent security group?
If you target a security group that does not exist in Active Directory, the preference item will never apply. The system will ignore the item because no users match the filter. Always verify the existence of the target group before finalizing the GPO settings.
Does refreshing Group Policy update Drive Maps immediately?
Yes, running gpupdate /force will force the client to re-evaluate GPO settings, including Drive Maps. However, mapped drives typically require a logoff and logon cycle to fully refresh or disconnect old mappings. A simple refresh may not remove a previously mapped drive.
How do I troubleshoot if the Drive Map applies but fails to connect?
Check the Event Viewer under Applications and Services Logs > Microsoft > Windows > GroupPolicy. Look for error events related to preferences. Also, verify that the network path is reachable from the client machine and that the user has read permissions on the shared folder.
