SCCM 1906 Known Issues – Not Fixed Yet?

There are some known issues which SCCM 1906 as per the Microsoft documentation. Some of them are just warning so that you can just ignore and/or perform workaround as mentioned below.

  • Peter blogged about the SCCM 1906 Azure AD Group Discovery bug. More details on his blog post –
  • SCCM 1906 Setup prerequisite warning on domain functional level on Server 2019
    • When installing the update SCCM 1906 in an environment with domain controllers running Windows Server 2019, the prerequisite check for domain functional level returns the following warning: –
    • [Completed with warning]:Verify that the Active Directory domain functional level is Windows Server 2003 or later
    • Workaround
      • Ignore the warning.
  • Azure AD user discovery and collection group sync don’t work after site expansion
    • If you then expand a standalone SCCM primary site to a hierarchy with a SCCM CAS, you’ll see the following error in SMS_AZUREAD_DISCOVERY_AGENT.log:
    • Could not obtain application secret for tenant xxxxx. If this is after a site expansion, please run "Renew Secret Key" from admin console.
    • Workaround
      • Renew the key associated with the app registration in Azure AD. For more information, see Renew secret key.
  • Ben (@RealBenBruno) updated me about the issue with SCCM 1906 & AirWatch Co-existence on Windows 10 device. They have been engaged with Microsoft techs for over a month about this. Ever since updating to 1902 and even 1906, if you are running a 3rd party mdm (we are using AirWatch) SCCM disables it’s own deployments and software center.

SCCM 1906 Client Fixes

The following are the SCCM client known issues fixed with SCCM 1906 production release.

  • After removing the Application Catalog role from a site, clients may continuously request a non-existent policy from the management point. This occurs because the associated web service policy is not correctly tombstoned on the client.
  • DataTransferService Jobs may fail if the client computer restarts while the job is still running. This occurs due to a timing issue during computer shutdown that results in an incorrect status being returned for a Background Intelligent Transfer Services (BITS) job.
  • A client may become unmanaged if it has a wi-fi profile certificate installed, and the client is installed using the cloud management gateway.
  • After performing an in-place upgrade of the operating system from Windows Server 2012 R2 to Windows Server 2016, the SCCM Health Evaluation scheduled task no longer functions. Client check results are reported as failed, and attempts to run the task from Task Scheduler result in the following error.
    • An error has occurred for task SCCM Health Evaluation. Error message: A task or folder with this name already exists.
  • An automated deployment rule (ADR) for an update package may fail if software update synchronization is removing expired content from the same package.
  • Clients are unable to download content or policies after repeated historical download failures. The data transfer service (DTS) jobs are suspended but restarting the SMS Agent Host (ccmexec) service causes downloads to resume. When the client is in this state, errors resembling the following are recorded in the DataTransferService.log on the client.
    • DTS job {guid} BITS job {guid 2} failed to download source file {filename}.exe to destination {client cache filename} with error 0x80072EE7
  • Users are unable to search in Software Center when the client operating system is configured with the Japanese locale and calendar.
  • User Deployments are not visible in Software Center when the client communicates with a Management Point that uses a replica database.
  • A remote control session to a SCCM client will fail within a few seconds of connection. This occurs if the Teredo tunneling adapter is enabled on the client.

SCCM 1906 Site System Fixes

SCCM 1906 known issues are listed down. SCCM 1906 production version comes with following fixes for Site system servers.

  • The SMSDPProv.log contains false errors when enhanced HTTP mode is not enabled. In this scenario, the error “Failed to verify if the cert is sccm issued, 0x800b0109” is not indicative of a problem state and can be ignored.
  • The list of SMS Providers is inconsistent after promoting a passive site server to active. The failover process succeeds, but remote providers are not listed in WMI or the Registry on the recently promoted site server.
  • When custom client settings are used, changes to User Device Affinity (UDA) settings are not applied unless the “User device affinity usage threshold (minutes)” setting is also changed.

SCCM 1906 Reporting Issues

SCCM 1906 fixes the slowness in the 2 default reports listed below.

  • The following reports may take significantly longer (hours) to run than expected because of an inefficiency in an associated SQL function
    • Software Distribution Content / All Active Content Distribution
    • Software Distribution – Content / Application Content Distribution Status



  1. since i upgraded to 1906, i have to frequently restart WMI service on my SMSPROVIDER Servers in order to fix console crash issue.

    and i also can’t download software updates anymore (patchdownloader says :
    ERROR: DownloadContentFiles() failed with hr=0x80041013

  2. Hi,
    Are you a ware about the below:

    Current version: 1906
    Scenario: Bare-Metal deployment – PXE
    Windows 10 deployment task sequence finish successfully but then I notice the following issue on the client:
    1- SCCM agent is installed
    2- SCCM client not receiving any policy from SCCM
    3- SCCM client showing on console with No agent installed
    4- I found “unknown computer” record on console
    this issue didn’t occur when I’m using Task Sequence Media (USB)

  3. After upgrading 2 labs and Production to 1906 I noticed that the Details pane in Distribution Point Configuration Status takes a very long to load and occasionally comes back with no results (I believe the query is timing out)

    Sometimes when it does load it has lots of messages that did not show here prior to 1906 and they have no status icon. For instance it is getting Notification Server Messages

    The query shows in SQL as an Expensive Query. I was able to copy the actual query and run it directly in SQL Management Studio and it took 3 1/2 minutes to complete.

    Have you seen this behavior? Any idea if Microsoft is aware? I did send a frown this morning and am waiting to see if they reply.

    select all SMS_DPStatusDetails.DPName,SMS_DPStatusDetails.ID,SMS_DPStatusDetails.InsString1,SMS_DPStatusDetails.InsString10,SMS_DPStatusDetails.InsString2,SMS_DPStatusDetails.InsString3,SMS_DPStatusDetails.InsString4,SMS_DPStatusDetails.InsString5,SMS_DPStatusDetails.InsString6,SMS_DPStatusDetails.InsString7,SMS_DPStatusDetails.InsString8,SMS_DPStatusDetails.InsString9,SMS_DPStatusDetails.LastStatusTime,SMS_DPStatusDetails.MessageCategory,SMS_DPStatusDetails.MessageFullID,SMS_DPStatusDetails.MessageID,SMS_DPStatusDetails.MessageSeverity,SMS_DPStatusDetails.MessageState,SMS_DPStatusDetails.NALPath,SMS_DPStatusDetails.PackageID,SMS_DPStatusDetails.SiteCode,SMS_DPStatusDetails.StatusMsgID from vSMS_DPStatusDetails AS SMS_DPStatusDetails where SMS_DPStatusDetails.NALPath = N'[“Display=\\\”]MSWNET:[“SMS_SITE=”]\\\’ OPTION(USE HINT(‘FORCE_LEGACY_CARDINALITY_ESTIMATION’))
