Don’t Enumerate Connected Users on Domain-joined Computers Policy using Intune

Here in his post, we will help you understand how to set the Don’t Enumerate Connected Users on Domain-joined Computers Policy Using Intune. We are going to use Configuration Profiles of Intune to implement this policy. Our main purpose here is to help you in acquiring knowledge of how to set the Don’t Enumerate Connected Users on Domain-joined Computers Policy Using Intune

Don’t Enumerate Connected Users on Domain-joined Computers Policy configuration blocks the enumeration of connected users on computers that are joined to the domain. Activating this policy will result in the Logon UI refraining from listing any connected users on domain-joined computers. If you choose not to set or deactivate this policy, domain-joined computers will continue to list connected users.

In a networked environment, where multiple computers are connected to a central domain, there are various security and access control considerations. One of these considerations is user enumeration, which refers to listing or identifying users currently connected to a specific computer or device.

A domain-joined computer is one that is connected to a centralized network domain, often managed by an organization’s IT department. This centralization helps in managing user accounts, access permissions, and other network-related configurations.

The policy setting being discussed aims to control whether the Logon User Interface (UI), the screen where users enter their login credentials, displays a list of connected users on domain-joined computers. If you enable this policy setting, then the Logon UI will not show a list of connected users on the domain-joined computer.

Intune MDM Event Log

To verify the successful implementation of String or integer policies on Windows 10 or 11 devices through Intune, you can leverage event IDs 813 and 814. These event IDs provide valuable insights into the application status of the policy as well as the specific value assigned to the policy on those devices. In the case of this particular policy, the value is String and is linked to the event ID 814.

By analyzing these event IDs, you can gain a clear understanding of the policy’s application status and the corresponding value associated with it on the devices in question.

To confirm this, you can check the Event log path – Applications and Services Logs – Microsoft – Windows – Devicemanagement-Enterprise-Diagnostics-Provider – Admin.

MDM PolicyManager: Set policy string, Policy: (DontEnumerateConnectedUsers), Area: (ADMX_Logon), EnrollmentID requesting merge: (1A661A16-302C-46D4-81F0-AA73244850D8), Current User: (Device), String: (<enabled/>), Enrollment Type: (0x6), Scope: (0x0).

So when I open the above Event log, I found that the policy I have applied to the device is successfully implemented. By reviewing the log entry shown in the above image, the Event Viewer, I came across essential information, including the Area and Enrollment ID. These details play a significant role in identifying the corresponding registry path. To locate the specific information, please consult the table provided below:

Area	Policy	String	Scoped	Event ID
ADMX_Logon	DontEnumerateConnectedUsers	Enabled	Device	814

The details presented in the table above for the Don’t Enumerate Connected Users on Domain-joined Computers Policy Using Intune can be employed to access the registry settings that hold the group policy configurations on a specific computer. To accomplish this, you can execute “REGEDIT.exe” on the target computer and navigate to the precise registry path where these settings are stored.

• Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\providers\1A661A16-302C-46D4-81F0-AA73244850D8\default\Device\ADMX_Logon

When you navigate the above path in the Registry Editor, you will find the registry key named DontEnumerateConnectedUsers. Also, when I navigated to the above path, I saw that the Registry Key was created.

Registry Name	Value
DontEnumerateConnectedUsers	Enabled
