Moving from Windows Server 2022 to 2025
And by moving I mean stand up a completely fresh Windows Server 2025 as the old server was patched for one too many times. (painfully slow and stuffy) What I figured out so far, is to install Windows Server 2025, and the exact same SQL Server 1:1 to the build # install ODBC v18 update current MECM to the latest and its OS (update other Microsoft products with windows update) go to sites / maintenance tasks and do an export robocopy the "software" folder as is Now next would be to shut down old MECM server, rename new to the old's hostname, and start the "recover site" What my concern is as always "What if" can I at this point or once I set up the new MECM up and running go back by shutting down this new server, and powering on the old (leave and rejoin domain for trust) and go back to business as usual? That if anything goes sideways, or things won't get better. By that i mean speeding up things which is the main reason of the 'move' which now I do not wish to troubleshoot. Our environment, database size is 7.9 Gb, which is far from being big. The reason must be the update over upgrade over update over 15 years or more no and never brand new OS. I can take care of the "how to" I know exactly how to recover a site 'on paper'. I just want to know there's no such thing as point of no return. (when not making a single change in the Db/console) I also understand I should not make any changes in the Db (console) while testing, which is no problem at all. All we use MECM for is staging computers. Nothing else really. Like nothing else at all. PXE. The end. Thanks for the inputs. (I hope I picked the right tags)
Existing required application deployments policy is not sent to devices
I have couple hundred applications in SCCM/MCM that are set to required and whenever there is a new device is built, all these required applications automatically get installed. I am on 2503 and 5 days ago i started seeing this issue. But if modify that deployment with current date and time then the application gets deployed right away if i run Application Deployment evaluation cycle. I also tested by deleting the existing deployment and created a new required deployment and run Application Deployment evaluation cycle then the application installs right away. The problem seems like the Primary server is not sending the policy to the client for existing deployments. The application compliance that we see for every deployment under Monitoring for all the devices moved to Error with Success. Not sure why this is happening. All these changes i noticed in the last one week. A week ago all these Already Compliant and Success status device count is under Success tab. Let me know if you have any suggestions.
MECM OSD TS Application Installations fail randomly to download content.
We are experiencing a persistent and well-documented issue with MECM OSD Task Sequences where Applications randomly fail to install after the MECM client has been installed. This behavior seems to affect many environments and has been an ongoing problem for years, yet a definitive solution remains elusive. In our case, we have over 30 Applications included in the OSD Task Sequence. Despite implementing all commonly recommended mitigations—such as inserting an additional restart after the MECM client installation and including a two-minute delay before the Application install task group begins—we still encounter random failures. The issue is not limited to any specific Application; it can be any one of the 30+ Apps, and the failure to download appears to occur entirely at random. Occasionally, most of the Applications install successfully, and only one will fail, which subsequently causes the entire Task Sequence to fail with the same error. Importantly, all of these Applications install without any issues post-OSD, further confirming that the problem lies not with the Applications themselves but with the process during the Task Sequence. The randomness of which App fails also suggests an underlying process, feature, or timing issue—not an App configuration problem. We have thoroughly validated all related infrastructure settings: Boundaries and boundary groups have been triple-checked. No boundary is assigned to multiple groups. Site system assignments are correct. We are using PKI certificates and HTTPS, and the client authentication certificate is present on the device at the time of failure. The issue has been replicated across both Windows 10 and Windows 11, ruling out any specific cumulative updates or OS version anomalies. No additional language packs are being installed—only language fallback is applied via the "Apply Windows Settings" step. One suspicious observation is the lack of any reference to our local Distribution Point in the LocationServices or CAS logs during failure events. Initially, this pointed to a possible boundary misconfiguration, but after multiple checks, no issues have been identified. Unfortunately, we are unable to use the common workaround of converting Applications to Packages, due to internal policies and deployment requirements. Therefore, we need to resolve this while continuing to use Applications in the Task Sequence. Given the number of years this issue has persisted across customer environments, it's surprising there isn’t more formal guidance or documentation available to help isolate the root cause. If anyone has encountered a similar scenario or has any advanced troubleshooting tips, we would greatly appreciate your insight.Applications deployed on device based collection are missing from devices.
Hey guys, In my SCCM environment we are facing an issue. Its a co-managed environment where apps are deployed via SCCM. All of a sudden the apps deployed on Device based collection are not reaching the end user devices. The policies related to these app are also not reaching the device. The compliance status for these apps also went down even though if it is installed on the device the SCCM reports as Non-Compliant\Error. Has anyone faced this issue or can help me to identify what could be causing the issue.
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.Access collections information locally
Is there a way through WMI/Microsoft.SMS.Client comobject to access information from the computer if is in a collection (cached information or otherwise)? I'm not sure if a computer gathers that information somewhere. I can't access that information on the site server or through the AdminService as the account running the commands would be the SYSTEM account. My goal is query if a computer is in a collection and install a piece of software through a task sequence.
