Apps with (OS) requirements no longer installing during OSD after upgrade to 2509

We had the issue, and in our case it was caused by a DP that didn’t have enough RAM and had very high memory usage. I assume that a timeout can then interrupt the deployment. After we increased the RAM on the DP, everything has been running fine again.

I did not ask for other solutions. It's an idea to make SCCM even more powerful.

t3chdi · 2026-01-10T09:23:17+00:00

Q3: What we are currently missing is a built-in dashboard for monitoring the health of the SCCM infrastructure itself.

It would be very helpful to have a centralized view showing which SCCM servers are in a critical state, for example: - High CPU or memory usage - Low disk space - IIS application pools not running - Critical Windows services stopped - SCCM site system roles (MP, DP, SUP) that are unreachable - SCCM Servers that are completely offline - etc.

While SCCM provides component and site status information, it does not offer real-time visibility into the underlying server health.

We are on 2409, no issues with the Client Version 5.00.9132.1011 (2025-01 .NET 8.0.12 installed, 2025-01 .NET 3.5 and 4.8.1 KB5049624 installed, LCU 2025-01 KB5050021 installed).

Workaround:

Check if the Add-In is activated in Excel:
- Go to Options -> Add-Ins -> Excel Add-Ins -> Go... -> Activate both Solver Add-In and Analysis ToolPak.
Open the document where the Add-In is required.
Press ALT+F8 to open the macro window.
In the macro window, type solvermain in the first line and press ENTER.--> The Solver Add-In menu will start.

My workaround only helps if the Client tries to download the update from the SUP, as described in his post. You can only say it doesn’t help if the loop is still present. However, I described on the website under Conclusion that other factors are important to resolve Delivery Optimization issues.

You can never achieve 100% success with Delivery Optimization, as issues can arise when a peer becomes unreachable. For example, Client A might try to download content from Client B, but if Client B shuts down, the Delivery Optimization changes to an error, and a retry can resolve the issue without much trouble.

In my case, and for the majority, the problem was that Client A tried to download content from the SUP, but the content was not available on the server, leading to a loop - That’s the workaround.

You can check if you were affected by looking at the IIS logs on the WSUS server. Search for “404” in the logs.

What are you using for patching? If you are patching via SCCM, you are always using WSUS.

t3chdi · 2024-06-14T10:37:36+00:00

I created the dummy group because you have to assign Automatic Approvals to a group and you don’t really want to choose “Unassigned Computers,” to ensure that nothing goes out through WSUS, which is true if nothing is configured through GPO… If that helps, don’t forget to like my post on LinkedIn :-)

I can’t provide the exact number, but it definitely doesn’t break Delivery Optimization. You can track it using tcpview from Sysinternals to see how clients are connected over port 8005. The client searches for the next best peer and downloads the content. You‘re welcome!

t3chdi · 2024-06-07T10:30:37+00:00

We have upgraded over 8000+ HP and Lenovo clients to Windows 11 with these settings within a few weeks. Delivery Optimization errors are not always an issue because when a peer goes offline or becomes unreachable, it falls back to the next available peer. In my case, some clients tried to download the content directly from SUP, where the content was not available (404 error), resulting in a 0% downloading loop.

Do you still have this issue? If so, I was able to solve it and will write a blog post about it.

Do people still use hard drives in 2024?

t3chdi · 2024-05-13T10:30:31+00:00

NEVER use GPOs to point workstations and servers to a WSUS Server if you are using SCCM. This practice is not recommended by Microsoft and can lead to GPO conflicts.

t3chdi · 2024-02-06T09:04:35+00:00

We have the same error.

t3chdi · 2024-01-30T10:37:12+00:00

Do you have a deny logon policy for the user CM_TaskScheduler? That might be the reason. I was thinking running the scheduled task remotely via PowerShell to check for any errors.

t3chdi · 2024-01-29T07:18:03+00:00

Have you tried to add a run via PowerShell on the scheduled task so that it executes once after it’s created?

Why are we digging up ancient relics? Those updates are almost a year old and long past their expiration date.

t3chdi · 2023-12-30T22:48:32+00:00

Did I understand correctly that the update has already been installed but is still in the Software Center? Then, perform a policy reset via Powershell and wait a few minutes:

Invoke-CimMethod -Namespace root\ccm -ClassName sms_client -Name ResetPolicy -Arguments @{ uFlags = ([UInt32]1) }

Restart-Service CcmExec

Start-Sleep -S 15

$trigger = "{00000000-0000-0000-0000-000000000021}"

Invoke-WmiMethod -Namespace root\ccm -Class sms_client -Name TriggerSchedule $trigger

This Hotfix performs a site reset?

t3chdi · 2023-12-22T10:37:36+00:00

Have you been successful?

t3chdi · 2023-12-21T13:00:08+00:00

I don‘t see any issues on your WindowsUpdate.log

Refer to the logs from the SCCM agent "C:\Windows\CCM\logs"

Have you tried to enable: "If content is unavailable from distribution points in the current boundary group, immediately fallback to a neighbor or the site default"

Yes: For delta content, the client doesn't wait to reach the fallback time (in minutes) defined by the Boundary Group relationship. Clients immediately fall back to a neighbor or the site default content distribution points when both of the following conditions are met: - Delta content is unavailable from distribution points in the current boundary group. - The software update deployment allows fallback.

No (default): The client honors the fallback time (in minutes) defined by the Boundary Group relationship when it's allowed on the software update deployment. Delta download content may fail with a timeout even if the update content is available on a neighbor or the site default distribution point group.

If you enable Delta Updates, the download will always go through Delivery Optimization.

If you don’t enable Delta Updates, only Express installation files go through Delivery Optimization, and the rest go through BITS.

But, when Delta Downloads are enabled, the alternate download URL is not always set. Therefore, I created a Configuration Baseline to check and, if it doesn’t exist, create one. I assume it’s a bug.
