Release Notes
In brief
The release notes now document that ODBC Driver 18.7.1.1 can block site configuration on Configuration Manager 2603 and earlier during an upgrade to version 2609. They recommend using validated driver version 18.6.2.1 instead.
What Intune admins need to know
Before upgrading, verify the ODBC driver version and avoid installing 18.7.1.1; use 18.6.2.1 to prevent the configuration block.
This summary was assembled from the tracked documentation change. Verify important details in the full Microsoft Learn article.

Client management
Clients aren't able download content from CMG when branch cache is enabled
Applies to: version 2403
After Branch Cache is enabled on primary sites, clients are unable to download apps and packages from the cloud management gateway (CMG). They typically manage to download only 20-30% of the content before the process gets stuck. In some cases, after downloading certain blocks of packages from the CMG, clients look for Branch Cache to retrieve the remaining content. However, none of the clients are able to download the complete content from the CMG, which prevents others from using Branch Cache to access it. The CTM.log on the client includes entries similar to the following:
(CTM.log - CTMJob({63B4C4CE-2DC4-4062-93C7-E5019B3B6CE1}): CCTMJob::Start - State=DownloadingContentFromPeers)
CTM.log _- CTMJob({D21758B0-D895-474E-9695-1023A25A1770}): CCTMJob::_PerformDownloadWithOutBranchCache - Download failure using branchcache, fallback to regular download
To work around this issue, disable branch cache.
Note
Clients are able to download content from the on-premises distribution point when Branch Cache is enabled.
Endpoint Protection
Security configurations removed from Intune
Applies to: version 2309 with KB25858444 and later
Microsoft Defender security configurations are no longer managed with Microsoft Intune after updating to Configuration Manager version 2403, or installing the Update Rollup for 2309.
The symptom is seen as a drop in the Microsoft Security Score values when viewed in Intune. This issue happens because security policy configuration data is incorrectly removed from clients after Configuration Manager clients are upgraded.
An updated version of the Microsoft Security Client Policy Configuration Tool, ConfigSecurityPolicy.exe, is available to resolve the Endpoint Protection policy issue described in this note.
The updated tool, version 4.18.24040.4, is distributed with the April 2024 monthly Microsoft Defender platform update. At the time of this writing, the platform update is in the process of global distribution, and should be broadly available in all regions by May 17, 2024. Once the platform update is installed on affected clients, Endpoint Protection policies are reapplied from Intune within 8 hours. The "Manage Endpoint Protection client on client computers" setting in Configuration Manager can be changed back to "Yes" as required.

Set up and upgrade
ODBC driver checkversion 18.7.1.1 can block site configuration before updating to 2609
Applies to: upgrades to version 2609
Microsoft ODBC Driver for SQL Server version 18.7.1.1 has a known issue with Configuration Manager version 2603 and earlier that can block site configuration.
To avoid this issue, don't install ODBC driver version 18.7.1.1 before updating Configuration Manager. Use ODBC driver version 18.6.2.1, the validated version shipped with Configuration Manager 2609, for the update. Complete the Configuration Manager update to version 2609 before you install ODBC driver version 18.7.1.1.
For more information, see ODBC driver for SQL Server.
Configuration Manager performance counters are missing on Windows Server 2025
Applies to: primary site servers and management points running Windows Server 2025
On Windows Server 2025, Configuration Manager performance counter registration can fail, leaving the counters unavailable in Performance Monitor. This issue can occur after a clean installation of Windows Server 2025 or an in-place upgrade from Windows Server 2022.
Perfsetup.log records errors similar to the following:
Error: InstallSMSObjectAndCounterKeySettingsIntoRegistry() could not get the "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SMS_SOFTWARE_INVENTORY_PROCESSOR\Performance" registry key; error = 6 (0x6).
Perfsetup can also exit with code 1000. The affected component name in the registry path can vary.
To resolve this issue, install the update rollup for Configuration Manager version 2603 (KB39169655) or update to Configuration Manager version 2609, which also includes this fix.
Client authentication and registration
Microsoft Entra token validation fails when the management point can't access the internet
Applies to: version 2603 and later
Starting in version 2603, the management point uses Microsoft Identity Service Essentials (MISE) for Microsoft Entra token validation and requires internet access. This requirement affects sites configured to support Microsoft Entra joined users and devices when clients authenticate using Microsoft Entra tokens, typically through a cloud management gateway (CMG). Environments that only use on-premises Active Directory authentication without Microsoft Entra integration aren't affected.
If the management point can't reach the required endpoints, CCM_STS_ManagedBase.log on the management point records a MiseAuthenticationTicketProviderException with an underlying network error, for example:
Microsoft.Identity.ServiceEssentials.Exceptions.MiseAuthenticationTicketProviderException: MISE12034: AuthenticationTicketProvider Name:AuthenticationTicketProvider
System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it
Important
The MISE12034 exception can also occur for other reasons. Before applying this resolution, verify that the underlying exception indicates a network connectivity problem, such as a SocketException, HttpRequestException, or connection timeout.
To resolve this issue, allow the management point server to access the following Microsoft Entra authentication endpoints through the proxy and firewall in the Local System context:
https://login.microsoftonline.comhttps://sts.windows.net
If the management point uses a proxy, configure it in the Local System context. In version 2603, the proxy set in the site system properties and a WinHTTP-only proxy (netsh winhttp set proxy) aren't used for this validation path.
For configuration steps and the full list of required endpoints, see Management point proxy configuration and Management point internet access requirements.
Bulk registration token verification fails after installing the version 2603 update rollup
Applies to: version 2603 with update rollup KB39169655 installed
After you install the update rollup for Configuration Manager version 2603 (KB39169655), bulk registration token verification fails on the management point for devices that aren't Microsoft Entra joined and connect through a cloud management gateway (CMG). Affected devices can't complete bulk registration through the CMG to obtain their individual Configuration Manager-issued client authentication tokens. Other CMG communication scenarios for these devices may also be affected.
This issue doesn't affect devices that use Microsoft Entra authentication or version 2603 sites that haven't installed KB39169655.
On the management point, errors similar to the following are recorded in <MP_InstallDir>\Logs\CCM_STS.log:
ProcessRequest - Start
Incoming request URL: https://<management-point>/CCM_STS

(Exception from HRESULT: 0x80131040)
To resolve this issue, install KB40345593, which is available in Updates and Servicing after you install KB39169655. This update requires a site reset after installation, but doesn't require a computer restart.
Collection management
Collections based on Active Directory group membership lose members after upgrading to version 2609
Applies to: version 2609
After you upgrade to Configuration Manager version 2609, a full Microsoft Entra user group discovery cycle might remove Active Directory user-group relationships from the Configuration Manager database. User collections with query-based membership rules that depend on Active Directory group membership might lose some or all members after collection evaluation. Deployments targeted to these collections might no longer reach the intended users.
To prevent further occurrences, disable Microsoft Entra user group discovery. Disabling discovery doesn't restore user-group relationships that have already been removed.
Software updates
Devices continue scanning Windows Update after moving the update workload back to Configuration Manager
Applies to: version 2503 with update rollup KB32851084 and KB36495448 installed, version 2509 with KB36495448 installed, and later
During site installation, the prerequisite checker looks for the minimum required version of the Microsoft ODBC driver. If the correct driver isn't detected the following message is recorded:
[Failed]: Install the Microsoft ODBC driver 18 for SQL setup from https://go.microsoft.com/fwlink/?linkid=2220989.
The link provided installs an older version of the ODBC driver; the correct link to use is: https://go.microsoft.com/fwlink/?linkid=2299909
Version 2107 update fails to download
Applies to: version 2107 and later
The update for Configuration Manager version 2107 is available to download, but it fails to download. The dmpdownloader.log on the service connection point has entries similar to the following:
Download large file with BITs
WARNING: EasySetupDownloadSinglePackage Failed with exception: The remote name could not be resolved: 'configmgrbits.azureedge.net'
WARNING: Retry in the next polling cycle
This failure happens because the service connection point can't communicate with the required internet endpoint, configmgrbits.azureedge.net. Confirm releases that the site system that hosts the service connection point role can communicate withinherit this internet endpoint. It was already required, but its use is expanded in version 2107. The site system can't download version 2107 or later unless your network allows traffic to this URL.
For more information, see internet access requirements for the service connection point.
OS deployment
PXE Responder isn't installed correctly after upgrading to 2403 in untrusted domain
Applies to: version 2403behavior
After upgradingyou move the Windows Update policies co-management workload from Intune back to 2403, site servers serving asConfiguration Manager, devices might continue scanning Windows Update or Microsoft Update instead of WSUS, even after a PXE responder mightmachine policy cycle completes.
Starting with KB36495448, the Configuration Manager client no longer sets or removes Windows Update scan source policies. Moving the workload slider doesn't automatically remove the Windows Update client policy state previously configured by Intune. This state can persist on the device after the Intune policy assignment is removed.
To address this issue, review the effective scan source for each update category and explicitly manage scan source policies through Group Policy or Intune. As a best practice, remove or reassign the device's Intune Windows Update client policy assignment before moving the workload back. For the cleanup procedure and alternative policy configuration, see failures due to incorrect configuration of the registry keys. We can observe the below failures in distmgr.log indicating that the registry keys weren't configured correctly.Moving the workload back to Configuration Manager.
Failed to get OS platform for server DP2.CONTOSO2.COM.Either a permissions issue or the server is not supported OS SMS_DISTRIBUTION_MANAGER
CDistributionManager::SetDpRegistry failed; 0x80070005 SMS_DISTRIBUTION_MANAGER
This happened due to currently unexplained failures in platform architecture identification that were introduced during the addition of support for arm64 machines to serve as remote distribution points.
Software updates
Reset default value of superseding age in months for software updates
Applies to: version 2303
Removing SUP role in Admin Console doesn't reset the superseding age property in WMI. As a result, while reconfiguring the role, the previously configured value is shown in the configuration window. This property needs to be reset to default value on role removal. For more information, see supersedence rules for installing a software update point.

User collections with query-based membership rules that depend on Active Directory group membership might lose some or all members after collection evaluation. Deployments targeted to these collections might no longer reach the intended users.
-The **OS Deployment Manager** built-in security role has permissions to [phased deployments](../../../../osd/deploy-use/create-phased-deployment-for-task-sequence). The following roles are missing these permissions:
+To prevent further occurrences, disable [Microsoft Entra user group discovery](../configure/configure-discovery-methods#bkmk_azuregroupdisco). Disabling discovery doesn't restore user-group relationships that have already been removed.
-- **Application Administrator**
-- **Application Deployment Manager**
-- **Software Update Manager**
-
-The **App Author** role can appear to have some permissions to phased deployments, but can't create deployments.
-
-A user with one these roles can start the Create Phased Deployment wizard, and can see phased deployments for an application or software update. They can't complete the wizard, or make any changes to an existing deployment.
-
-To work around this issue, create a custom security role. Copy an existing security role, and add the following permissions on the **Phased Deployment** object class:
-
-- Create
-- Delete
-- Modify
-- Read
-
-For more information, see [Create custom security roles](../configure/configure-role-based-administration#create-custom-security-roles)

-## Configuration Manager console

-### Intune RBAC for tenant attached devices
-
-*Applies to: version 2207*
+## Software updates
-***[Updated]***: There's a checkbox for a role-based access control (RBAC) setting in the [cloud attach configuration wizard](../../../../cloud-attach/enable) in the console. By default, Configuration Manager RBAC is enforced along with Intune RBAC when you're uploading your Configuration Manager devices to the cloud service. This checkbox is selected by default.
+### Devices continue scanning Windows Update after moving the update workload back to Configuration Manager
-You can now configure Intune role-based access control (RBAC) when interacting with [tenant attached devices](../../../../tenant-attach/client-details?toc=/mem/configmgr/cloud-attach/toc.json&bc=/mem/configmgr/cloud-attach/breadcrumb/toc.json) from the Microsoft Intune admin center. For more information, see [Intune role-based access control for tenant-attached clients](../../../../cloud-attach/use-intune-rbac).
+*Applies to: version 2503 with update rollup KB32851084 and KB36495448 installed, version 2509 with KB36495448 installed, and later releases that inherit this behavior*
-### Unable to open console because extension installation loops
+After you move the **Windows Update policies** co-management workload from Intune back to Configuration Manager, devices might continue scanning Windows Update or Microsoft Update instead of WSUS, even after a machine policy cycle completes.
-*Applies to: version 2111*
+Starting with [KB36495448](../../../../hotfix/2509/36495448), the Configuration Manager client no longer sets or removes Windows Update scan source policies. Moving the workload slider doesn't automatically remove the Windows Update client policy state previously configured by Intune. This state can persist on the device after the Intune policy assignment is removed.
-In certain circumstances, you're unable to open the console due to an extension installation loop. This issue occurs when two or more versions of a single extension were marked as [required for installation](../../manage/admin-console-extensions#require-installation-of-a-console-extension). This issue occurs for extensions imported through the wizard, from a PowerShell script, or through Community hub. If you use the **Make optional** setting before importing a new version of the extension, this issue doesn't occur.
+To address this issue, review the effective scan source for each update category and explicitly manage scan source policies through Group Policy or Intune. As a best practice, remove or reassign the device's Intune Windows Update client policy assignment before moving the workload back. For the cleanup procedure and alternative policy configuration, see [Moving the workload back to Configuration Manager](../../../../sum/deploy-use/integrate-windows-update-client-policies#moving-the-workload-back-to-configuration-manager).
-When you encounter this issue, it initially appears as a normal console extension installation. After the extension finishes installing, you select **Close** to restart the Configuration Manager console. When the console restarts, you're prompted to install the console extension again. The extension installation continues to loop and the Configuration Manager console doesn't fully open.
+### Reset default value of superseding age in months for software updates
-To both prevent and work around this issue, run the following SQL script on your CAS database and all of your primary site databases:
+*Applies to: version 2303*
-```sql
-ALTER VIEW vSMS_ConsoleExtensionMetadata
-AS
- WITH m AS(
- SELECT *,
- RN = ROW_NUMBER()OVER(PARTITION BY ID ORDER BY Version DESC)
- FROM ConsoleExtensionMetadata
- )
- SELECT
- m.ID,
- m.Name,
- m.Description,
- m.Author,
- m.Version,
- m.IsEnabled,
- m.IsApproved,
- m.CreatedTime,
- m.CreatedBy,
- m.UpdateTime,
- m.IsTombstoned,
- m.IsRequired,
- m.IsSigned,
- m.IsUnsignedAllowed,
- CASE m.IsRequired
- WHEN 0 THEN ''
- ELSE
- (
- SELECT top(1) author FROM ConsoleExtensionRevisionHistory h
- WHERE m.ID=h.ExtensionId AND m.Version=h.Version AND h.Changes & 1=1
- ORDER BY h.RevisionTime DESC
- )
- END AS RequiredBy,
- m.IsSetupDefined
- FROM m
- WHERE RN = 1
-GO
-```
+Removing SUP role in Admin Console doesn't reset the superseding age property in WMI. As a result, while reconfiguring the role, the previously configured value is shown in the configuration window. This property needs to be reset to default value on role removal.

-## Boundaries and Boundary groups
+## Cloud services
-### Clients not belonging to any boundary group can fail to download due to SQL issue
+### CMG update to version 2609 fails when Azure permissions or resource provider registration are missing
-*Applies to: version 2303, 2309 RTM*
+*Applies to: version 2609 updates with an existing cloud management gateway*
-Consider ConfigMgr hierarchy with a remote MP and CMG and you deploy an app to a device collection. The Clients can't download app, and reflect the following SQL permissions issue in **MP\_Location.log**.
+Starting in version 2609, Configuration Manager automatically disables shared-key access for cloud management gateway (CMG) storage. Existing CMGs that previously used shared-key access also require Azure role-assignment permissions and resource provider registration for this transition. A successful deployment on an earlier version doesn't confirm that these prerequisites are met.
-```log
- The SELECT permission was denied on the object 'vSMS_DefaultBoundaryGroup', database 'CM_xxx', schema 'dbo'.
-```
+If the CMG server application's service principal can't create the required storage role assignments, the CMG deployment update can fail. **CloudMgr.log** can report HTTP `403`, `DeploymentFailed`, and a denied `Microsoft.Authorization/roleAssignments/write` action. Missing **Microsoft.Maintenance** resource provider registration can also cause the deployment update to fail.
-To work around the issue run the following SQL script on the SQL database on the primary sites where the MP reports.
+Before updating, verify the CMG server application's effective permissions at each CMG resource group. The **Contributor** role alone doesn't grant storage role-assignment permissions, and the signed-in administrator's permissions don't establish that the CMG application has access. Use the constrained role-assignment configuration described in [Configure Azure RBAC permissions for the server app](../../../clients/manage/cmg/configure-azure-ad#configure-azure-rbac-permissions-for-the-server-app), rather than granting unrestricted administrator permissions.
-```sql
- GRANT SELECT ON vSMS_DefaultBoundaryGroup To smsdbrole_MP
-```\ No newline at end of file+Also verify that **Microsoft.Maintenance** is registered in every Azure subscription that hosts a CMG. Registration in a staging subscription doesn't register the provider in a different production subscription. For instructions, see [Configure Azure resource providers](../../../clients/manage/cmg/configure-azure-ad#configure-azure-resource-providers).\ No newline at end of file
