Hello,

We manage an on-premises Active Directory domain with Windows 10 and Windows 11 clients managed through Group Policy.

Recently, we started experiencing unexpected behavior across multiple workstations. We would like to identify the root cause before making any configuration changes or escalating the issue to our security team.

Issue 1: Unexpected ADMIN_ Profile Folders and Local Accounts

  • A standard domain user is signed in to a workstation.
  • When we right-click an administrative tool and select Run as administrator, then enter Domain Admin credentials, the credential prompt appears as a Windows Security dialog rather than the classic User Account Control (UAC) dialog we previously encountered.
  • After authentication, a new folder appears under C:\Users with a name such as ADMIN_<admin-username>.
  • A corresponding account also appears in the local Administrators group on the workstation.
  • This behavior occurs whenever we launch administrative applications using elevated credentials.
  • It affects multiple workstations and different administrative accounts. Each account used for elevation appears to result in a corresponding ADMIN_<username> folder and local account on the affected workstation.

We would like to understand whether these folders and accounts are expected Windows behavior or evidence of an unexpected configuration or authentication issue.

Issue 2: ADUC and Other Administrative Tools Fail to Authenticate Correctly

When we launch Active Directory Users and Computers (ADUC) using Run as administrator and enter valid Domain Admin credentials:

  • The Windows Security credential prompt repeatedly appears.
  • After several attempts, ADUC opens but does not connect to the domain.
  • The following error is displayed:

“To manage users and groups on this computer, use Local Users and Groups. To manage users, groups and computers in a domain, log on as a user with domain administration rights.”

Similar credential prompts and authentication failures occur with other Active Directory administrative tools and our antivirus management console when launched with elevated credentials.

Troubleshooting Performed and Pending Checks

  • We checked Event Viewer and did not find User Profile Service events 1511 or 1515 associated with this issue.
  • We have not knowingly changed any relevant Group Policy settings, registry values, or user profiles.
  • We are still investigating the TypeOfAdminApprovalMode registry value and the policy, if any, that controls it.
  • We are also checking whoami /all in the elevated session to determine which security identity and group memberships are actually being used.
  • We are verifying whether the issue also affects Windows 10 clients.
  • We have not yet conclusively identified whether the behavior originates from Group Policy, Intune, a security baseline, or a local configuration.

Our Current Hypothesis

We initially considered whether this could be related to Windows 11 Administrator Protection or another Windows security or elevation mechanism.

However, we have not confirmed that Administrator Protection is enabled, and we understand that the appearance of ADMIN_ folders alone does not establish that this feature is responsible.

We would appreciate guidance on identifying the actual mechanism that creates these accounts and profiles and causes the repeated credential prompts.

Questions

1. Expected behavior

Is the creation of ADMIN_<username> profile folders and corresponding local accounts an expected behavior of Windows 11 Administrator Protection when a standard domain user launches an application using Domain Admin credentials? If not, what other Windows mechanisms or configurations could explain this behavior?

2. Feature activation and configuration source

Can Administrator Protection or a related elevation feature be enabled or configured through Windows updates, Group Policy, Intune, or security baselines? What specific settings, policies, registry values, or logs should we examine to confirm whether this feature is enabled and identify its configuration source?

3. Organization-wide scope

Given that the issue affects multiple workstations and different administrative accounts, what is the recommended approach to determine whether the behavior is caused by a centrally applied configuration rather than individual device settings?

Would you recommend collecting Group Policy Results (gpresult), checking resultant policy settings, reviewing Intune device configuration and security policies, or examining specific Windows event logs?

4. Supported method for running RSAT tools

What is the recommended, supported method for launching ADUC and other RSAT tools with domain administrative credentials in this scenario?

How can we verify that the elevated process is using the intended domain identity and that domain authentication is functioning correctly, without weakening security controls?

5. Existing accounts and profile cleanup

If the responsible feature or configuration is subsequently disabled or corrected, should the existing ADMIN_ accounts and profile folders be removed?

If cleanup is necessary, what is the supported method for removing them safely without affecting legitimate local accounts, domain accounts, or existing user profiles?

Environment Details

  • Active Directory: On-premises domain
  • Client operating systems: Windows 10 and Windows 11
  • Device management: Group Policy
  • Centralized security management: Still being investigated
  • Scope: Multiple workstations and multiple administrative accounts
  • Exact Windows builds and policy values: Being collected

We are not attempting to bypass any security controls. Our objective is to identify the root cause, understand the intended Windows behavior, and determine the appropriate supported remediation before involving our security team.

We can provide sanitized command output, relevant policy results, Windows build information, and screenshots if needed.

This is happening because of Administrator Protection being turned on by October Patch. If your organization uses Windows security baselines, Administrator protection becomes enabled by default with the October 2026 Windows security update. Happened to our organisation & we applied below fix temporarily until MS fixes it.

Fix: Launch Registry edit using a local admin account on the PC & go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\TypeOfAdminApprovalMode and change value from 2 to 1. Reboot device.

2 = Administrator Protection enabled

1 = Administrator Protection turned off

Later you can package this up using Intune & deploy.

Root Cause: Your ADUC doesn't work because when you enter AD admin credential, Administrator Protection creates temporary local profile ADMIN_user. This ADMIN_user is a local account so your AD doesn't recognise this, hence you can't launch ADUC at all.

    What I observe is also UNC path is now not accessible. That is as expected ? Devices after october patching cannot be accessed remotely with UNC path as 'Access Denied' error appear. Is there a way to bypass this without changing TypeOfAdminApprovalMode to legacy ?

    Hello Mustafa,

    Thank you for posting your question on the Microsoft Windows Forum!

    Thank you for the detailed write-up and screenshots. Based on the information provided, I would focus less on Administrator Protection as the primary cause and more on understanding what is creating the ADMIN<username> local accounts_.

    What Stands Out

    The most unusual behavior here is not the credential prompt itself, but that:

    ADMIN_userA
    ADMIN_userB
    

    appear as separate local accounts in the local Administrators group and corresponding profile folders appear under:

    C:\Users\ADMIN_<username>
    

    That is not typical behavior for standard UAC elevation using Domain Admin credentials.

    When a domain administrator launches ADUC through Run as administrator, Windows normally creates an elevated token for that domain account. It does not normally create a new local user account and profile whose name starts with:

    ADMIN_
    

    Regarding Administrator Protection

    Your hypothesis is reasonable, because recent Windows security enhancements can change how administrative credentials are handled.

    However, the screenshots alone do not prove that Administrator Protection is responsible. In particular, the presence of persistent:

    ADMIN_<username>
    

    accounts in the local Administrators group suggests that either:

    • A centrally managed security solution is provisioning temporary administrative identities.
    • A third-party privileged access management (PAM/EPM) solution is involved.
    • A policy or security baseline is modifying administrative elevation behavior.

    Why ADUC May Be Failing

    The ADUC error:

    To manage users and groups on this computer, use Local Users and Groups...

    suggests the elevated process may not actually be running under the expected Domain Admin security context.

    The first thing I would want to verify is:

    whoami
    

    and:

    whoami /groups
    

    from inside the elevated ADUC session (or an elevated Command Prompt launched using the same credentials).

    That will tell you which identity Windows is truly using.

    Organization-Wide Scope

    Because you have:

    • Multiple endpoints affected
    • Multiple administrative accounts affected
    • The same account-naming convention (ADMIN_*) appearing across systems

    I would strongly suspect a centrally applied configuration rather than local corruption.

    For that reason, I think your planned investigation is exactly the right direction:

    • gpresult /h
    • Resultant Set of Policy (RSoP)
    • Security baselines
    • Intune policies (if present)
    • Endpoint privilege-management products
    • Privileged-access tooling

    My Assessment

    Based on the screenshots and symptoms:

    This does not look like a user profile corruption issue.

    This does not look like a DNS or domain trust issue.

    The repeated prompts and ADUC failure are likely secondary symptoms.

    The ADMIN_<username> accounts are the most important clue in the case.

    Before changing policies or deleting profiles, I would first determine:

    What component is creating and managing the ADMIN<username> accounts?_

    Because those accounts do not resemble the normal behavior of a workstation simply elevating a domain administrator through UAC.

    Questions

    Could you confirm whether your environment uses any of the following?

    • Microsoft Intune Endpoint Privilege Management (EPM)
    • BeyondTrust
    • CyberArk
    • Delinea (formerly Thycotic)
    • Admin By Request
    • AutoElevate
    • Any PAM/EPM solution

    The naming pattern:

    ADMIN_<username>
    

    looks very similar to what I would expect from a privilege-management workflow rather than native Active Directory administration.
