Windows Server Update Services 2022 update problem with the message: (0x8024401f)

Hi Cloud Admin Ercan Boral,

The error code 0x8024401f typically points to a communication issue between WSUS and Microsoft Update servers, often triggered by metadata corruption or a failed update to WSUS components. The fact that you’re seeing an entry labeled “Windows 0.0” strongly suggests a metadata issue introduced by the February 18th update.

At this point, I recommend checking the WSUS synchronization logs (WSUSCtrl.log and SoftwareDistribution.log) to confirm whether metadata download is failing. Clearing the WSUS cache and re‑running synchronization can sometimes resolve this. You may also need to reapply the latest WSUS cumulative update or hotfix, as Microsoft has acknowledged issues with certain WSUS builds where metadata parsing fails after updates. If IIS reset and SUP checks did not help, re‑installing the WSUS role update or applying the latest servicing stack update for Windows Server 2022 may be necessary.

For diagnostics, please collect WSUSCtrl.log, WsyncMgr.log, and Application Event Logs from the WSUS server. These will help confirm whether the metadata corruption is the root cause. If the issue persists, Microsoft recommends re‑indexing the WSUS database and running the WSUS cleanup wizard to remove invalid entries.

I hope the response provided some helpful insight. If it clarified the issue for you, please consider marking it as Accept Answer so others with the same issue can find the solution. If you need further information, feel free to leave a comment.

There is a known WSUS-related change in recent Windows updates, but the only documented behavioral change in the provided context is that WSUS no longer shows synchronization error details in its own console after installing KB5070881 or later. This was done to mitigate CVE-2025-59287 and does not itself stop synchronization; it only removes detailed error reporting in WSUS.

From the available information, the following points can be confirmed:

1. Known WSUS issue around February 2026
   • After installing KB5070881 (October 23, 2025) or later, WSUS no longer displays synchronization error details in its error reporting. This behavior is still present in the February 10, 2026 cumulative update KB5075899.
   • This affects visibility of sync errors but does not state that synchronization or client updating is blocked.
2. Logs and diagnostic data to collect Based on WSUS troubleshooting guidance in the context, the following logs and data are relevant:
   • WSUS server logs:
     • %ProgramFiles%\Update Services\LogFiles\SoftwareDistribution.log (used to verify protocol/TLS behavior and sync failures).
   • IIS/WSUS startup behavior:
     • After restarting the WSUS service and running iisreset, check SoftwareDistribution.log for entries starting with SCHANNEL Protocol to confirm which TLS versions are enabled.
   • Network and TLS behavior:
     • If synchronization with Microsoft endpoints fails, a network capture can show whether the WSUS server is attempting to use an unsupported TLS version (for example, TLS 1.0) and receiving resets from the Microsoft update endpoint.
3. Steps to resolve WSUS sync/update failures (0x8024401f context) The context specifically documents a class of WSUS sync failures caused by TLS configuration on WSUS servers that cannot negotiate TLS 1.2 with Microsoft update endpoints:
   • On Windows Server 2012 / 2012 R2 WSUS, synchronization fails if only security-only updates are installed and the Monthly Rollups that enable TLS 1.2 support are missing. In that case, the WSUS server attempts TLS 1.0, the Microsoft endpoint resets the connection, and synchronization repeatedly fails.
   • The documented resolution for that scenario is:
     1. Install the latest Monthly Rollup for the WSUS server OS so that TLS 1.2 is fully enabled for WSUS.
     2. Apply the additional fix described as “Resolution for issue 1” in the same troubleshooting article to avoid manual import failures.
   While the OS version in that example is Windows Server 2012/2012 R2, the pattern is:
   • Ensure the WSUS server has all required OS updates so that TLS 1.2 is enabled and used for connections to https://sws.update.microsoft.com.
   • Confirm via SoftwareDistribution.log that older protocols (TLS 1.0/1.1) are disabled and TLS 1.2 is enabled.
   Concretely, using the documented steps:
   1. On the WSUS server, restart the WSUS service.
   2. Run iisreset from an elevated command prompt.
   3. Open the WSUS console and connect to the server so that WSUS goes through its startup sequence.
   4. Open %ProgramFiles%\Update Services\LogFiles\SoftwareDistribution.log and search for lines beginning with SCHANNEL Protocol to verify which TLS versions are enabled.
   5. If the log does not show TLS 1.2 as enabled, install the latest cumulative/rollup updates for the WSUS server OS so that TLS 1.2 is available and enabled, then repeat the steps above.

Because the provided context does not contain a specific mapping of error 0x8024401f to a precise WSUS-side root cause on Windows Server 2022, only the general, documented WSUS sync/TLS troubleshooting and the known limitation on WSUS error visibility after KB5070881/KB5075899 can be stated.
