Using REST API to get / set device variables
Hi, I'm trying to set a couple of variables against a machine name, through using the REST API. These are the variables that are set that you can see in the console if you right click properties on a device and go to the 'Variables' tab. These are handy because they can later be referenced during Task Sequences / OSD. I just can't figure out how to do it with the REST API. I have no issues doing it with the powershell module using the 'New-CMDeviceVariable' command, but my solution i'm building at the moment requires the solution to be done with rest api, not with ps modules... I can connect to REST API using powershell using commands such as the below. This all works fine. $ConfigMgrServerURL = "https://SCCMserver.domain.local" $MachineName = "MachineName1" # Following command is a sample GET request, which works. (Invoke-RestMethod -Method Get -Uri "$ConfigMgrServerURL/AdminService/wmi/SMS_R_System?`$filter=Name eq '$MachineName'" -Credential $Credential) #I can also fetch "Custom Properties" via this command (Invoke-RestMethod -Method Get -Uri "$ConfigMgrServerURL/AdminService/v1.0/Device($ResourceID)/AdminService.GetExtensionData" -Credential $Credential) Now i just can't see where i can go to set a variable on the machine. Does anyone have any ideas ? Thanks!
Win11 24H2 slow to restart TS task execution following reboot task in bare metal OS deployment
When comparing OS deployment bare metal task sequence times between Windows 11 24H2 and Windows 10 22H2 I could see that 24H2 was considerably slower even though the task sequences were almost identical other than the OS being laid down on the device. I did a timing comparison and noticed two things in particularly that were taking considerably longer on the 24H2 device: 1) reboot tasks 2) time to finish up the task sequence work after the last step. For reboot tasks, I can see that the delay is between these two events in the SMSTS.log log: Waiting for policy to be compiled in 'root\ccm\policy\machine' namespace and Policy verification done within the OSDSetupHook component. On the Windows 10 device the time between those log entries was 1 second, but on Windows 11 24H2 those log entries vary, but it's usually around 2 minutes. At the end of the task sequence, after executing the last task, following The task execution engine successfully completed the current task sequence step smsts.log entry to when the smsts.log stops being written to, it takes 14 seconds for the Windows 10 device, but it takes 4:29 seconds for the Windows 11 device. The delays are similar, between these two events in SMSTS.log (see attached screen shot): End Task Sequence policy cleanup and Policy evaluation initiated within the TSManager component. Any reason policy work should take considerably longer on Win11 24H2? Any suggestions on where I can look to see as to why it's taking such a longer time to deal with policy work in 24H2? Is this a Win11 24H2 issue, a ConfigMan issue, or ConfigMan configuration issue? I am welcome to entertain any thoughts or suggestions folks have. Anyone else seeing this issue in their environment? Environment details: CM 2503 (5.0.9135.1000) without KB33177653 or KB34503790 installed. Windows 11 = 24H2 customized reference image built from August 2025 ISO. ADK = 21H2 (10.1.22000.1).
SCCM software update install error 0x8007139F
While trying to install the monthly September patch Tuesday updates, e.g. 2025-09 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5065426) (26100.6584) and 2025-09 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 for x64 (KB5064401) would often fail on many machines with error code 0x8007139F. Every single time this would happen, the update will always install on a retry. That's if the issue happened at all, but it happened on around 60% of the endpoints this month in the test deployment group. It appeared to happen to both updates. Based on the error description, it states that the group. or resource is not in the correct state to perform the requested operation. I couldn't find any documentation of this issue for other people using SCCM. I already tried resetting windows update components, running sfc /scannow, and the DISM restore image command which all completed successfully, but nothing has fixed the issue so far. Any help would be greatly appreciated.
Windows/Defender Updates not deployed to SCCM server (all clients work fine!)
After battling for a few weeks with this it finally occurred to me to reach out for help, and I found this forum. So here goes… I have a relatively small environment with Windows Updates managed by SCCM. Currently, all clients are receiving updates as expected, the only client that isn’t is the Windows Server that’s hosting SCCM itself. Should I be configuring the winhttp proxy settings on that one server to point to our proxy (I have tried it and it didn’t seem to make a difference)? Without the winhttp proxy set, when I check the Windows update log, it seems to be trying the automatic proxy settings and quite rightly failing. It runs out of options and tries the user proxy as a last resort. I have checked that I can reach the URL configured in the Windows Update settings in Group Policy from the SCCM server and it works fine. Is there something I need to do differently with the SCCM server versus all the other clients? The SCCM client is installed on the SCCM server and is reporting healthy status with expected policies applied like all other managed clients in the estate. The SCCM server is in the same boundary as other servers that are receiving updates. SCCM 2503 running on Windows Server 2019. WSUS is running on the same server. The Software Update Point is configured with proxy settings. Thanks in advance!!Unable to import drivers into SCCM 2503
While trying to import the LAN drivers into SCCM version 2503, I encountered an error. The errors are, 1. Error: Some driver(s) can not be imported successfully. 2. Error: Failed to import the following drivers: • Realtek PCIe GbE Family Controller - An error occurred while importing the selected driver. Can anyone help me resolve this issue?
Application auto upgrade not working
Hello, I'm trying to deploy applications with auto upgrade but nothing happens. Let me explain what I'm doing : App_V1 is deployed as available to a user collection I install the app, nothing special here App_V2 is set to supersede App_V1 with uninstall checkbox (I need that in my environment) I deploy App_V2 as available to the same user collection with the checkbox "Automatically upgrade any superseded versions of the application" In the software center, I can see App_V2 with the install button (App_V1 is hidden, expected), but nothing else happens If I check the logs, I can see in PolicyAgent.log : A line starting with "Compiling policy <deploymentID>/supersedence..." Then a line starting with "Raising event: instance of CCM_PolicyAgent_AssignmentDisabled...<some assignment info> Nothing else I don't know how to further troubleshoot that situation. Can someone give me some clues ? ThanksRe-Join SCCM Client to Intune for Co-Managed join Type
Hello, I have been using SCCM for a long time, I have it is setup for Co-management, and all my workloads are moved over to Intune. I have a few clients that for one reason or other have not been added to Intune. I can get them onboarded, but the join type always ends up Intune. I am trying to find out the correct recipe to reenroll an SCCM client to Intune. I have tried uninstalling the SCCM client and reinstalling. I have tried removing registry keys for Intune to ensure it joins again. I have used DSREGCMD to leave and join back. I have completely removed from Domain and deleted from Intune. I have tried combinations of all of these things together. I have yet to come up with a specific order to do them in. I still think there is some remnant that is preventing a rejoin. Does anyone have details that help me to get systems to rejoin via SCCM? Some may say what is the difference. The difference is there are tools that are not present if the Join type is incorrect. Best regards and thanks.
How to determine what a Package ID is associated with
We have hundreds of packages, applications, software update packages, driver packages, OS images, etc. There are times I only have a package ID and I need to determine what it is. A royal pain to manually search each one of those categories in the console. Anyone have a Powershell script to find what the package ID is associated with?
