PENDING Configuration manager client certificate switch to none after windows feature update

[Bunny007]

Hi,

Configuration Manager client certificate is set to none after the Windows feature update. It was on PKI before the update and working fine. The client show's online in the console and is getting all the updates but the certificate is set to none.


In the policy logs, it says that the client is not registered.

Which feature update was deployed ?.

Windows feature update 2004. It works fine when I roll back to the previous version of windows 1909.

Just noticed that issue is happening on random devices after the windows update. It's not just limited to devices updating from 1909 to 2004.

Upon checking the ClientIDManagerStartup.log i found that the client fails to send the registation request message.

Any recomendation?
