Subsequent device registration in Intune
- Aug 01, 2025
Hello,
if anyone else needs this. I did the follwing on every single device:- Opend an cmd via Endpoint Security Software Live Response in System Context
- Executed C:\Windows\system32\deviceenroller.exe /c /AutoEnrollMDM
- To be secure - opened powershell.exe and set the MDM URLs
$key = 'SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\*'
$keyinfo = Get-Item "HKLM:\$key"
$url = $keyinfo.name
$url = $url.Split("\")[-1]
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\\$url"New-ItemProperty -LiteralPath $path -Name 'MdmEnrollmentUrl' -Value 'https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmTermsOfUseUrl' -Value 'https://portal.manage.microsoft.com/TermsofUse.aspx' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmComplianceUrl' -Value 'https://portal.manage.microsoft.com/?portalAction=Compliance' -PropertyType String -Force -ea SilentlyContinue; - C:\Windows\system32\deviceenroller.exe /c /AutoEnrollMDM
- Checkt everything with dsregcmd /status
Now waited 10-15 Minutes. The devices appeared first in Entra with Intune as MDM. Than they appeared in Intune.
It was a lot oft work to execute those commands on every single device. But it was better than opening a Remote maintenance on every dev
Hy,
so this is one of the most common errors when setting up MDM/Intune initially. I am struggling with a migration to almost the same issue, except in my case the devices are registered and not joined. 🙃
Recommendation, If you have the possibility test it first in a DEV/Test Tenant.
1. Enable Automatic MDM Enrollment
- Update the MDM user scope:
In the Microsoft Entra admin center, navigate to
Devices > Enrollment > Windows enrollment > Automatic Enrollment.
Set the MDM user scope to All (recommended for automation) or to a security group containing your users.
2. Assign an Intune License
- Ensure that all users signing into these devices have an appropriate Intune license assigned (e.g., Microsoft 365 E3/E5, EMS E3/E5, or standalone Intune)
Options to trigger enrollment:
1. Local User Action (Manual, but least disruptive)
- On each device, instruct users to:
- Go to Settings > Accounts > Access work or school
- Click their work account, choose Info, and select Sync or Enroll only in device management
(This triggers MDM enrollment without rejoining the device or wiping data)
2. Automated Script or Group Policy
- You can deploy an MDM enrollment Group Policy to all affected devices:
- Use the Group Policy Management Editor:
- Navigate to:
Computer Configuration > Policies > Administrative Templates > Windows Components > MDM - Enable the policy:
Enable automatic MDM enrollment using default Azure AD credentials - Set Device Credential and target it at the appropriate devices.
- Navigate to:
- Use the Group Policy Management Editor:
FYI
There is no Microsoft-supported “bulk retroactive auto-enrollment” button for previously Entra-joined devices. All automated options use either a user-side action or a domain-wide Group Policy to trigger MDM enrollment post-facto.
Good luck!

Hello,
thanks for your reply. I already know the points you mentioned. Unfortunately my colleagues don't know this. Now i have to correct the settings. With hundreds of costumer tenants and devices it woult be a lot of work.
Do you if it is possible to register a device in intune, when i have access to cmd or ps of a device with system context?
I know the following opportunities:
- Entra Join with User
- psexec and
%windir%\system32\deviceenroller.exe /c /AutoEnrollMDM
- dsregcmd /leave /join
- GPO
- Browser: ms-device-enrollment:?mode=mdm
Can i use on of those without use credentials? Only to bring the device to Intune.
Thanks.
