TPM error - SCEP Certificate enrollment initialization failed

[yvesgeiser]

Hello,

My current pretty much new setup (AMD 5800x, ROG Strix X570-E Gaming, Samsung 980pro disk, Trident Z Ram's, Logitech periphery) throws many SCEP error messages when Windows 11 is installed.

Those messages look like this:

SCEP Certificate enrollment initialization for SYSTEMNAME via https://AMD-KeyId-578c545f7969514212...lates/Aik/scep failed:

GetCACaps
GetCACaps: Not Found

Does anyone know how to solve this? I managed to enable all items and my system is absolutely up to date when it comes to drivers. The OS reports all is fine with TPM. Keys are correctly set.

Hi!

I had the same problem after I did a clean install of windows 11 with my 5900x and Dark hero MB. I soon had problems with intermittent random freezing, no bluescreen, everything would just freeze and I had to manually reboot. Not a hundred % sure it was due to the error but when I googled the error I found a couple of threads regarding the same thing. Tried some of the suggestions but none worked. This in combo with some other issues I had I decided to reinstalled windows 10 instead. Rock solid now.

There is this thread here that suggests to stop a scheduled task : Search for "Task Scheduler" ->drop "Microsoft" ->drop "Windows" ->click "CertificateServiceClient" -> set the "AikCertEnrollTask" to disabled.

That will make the event viewer message disappear.

I have some experience with certificates and also attempted to perform the enrollment directly from the command prompt, using a copy of the certificate retrieved from Microsoft, but no joy, even with the mentioned certificate correctly installed in the TPM area it still logs that error.

Note that the TPM is used only for SecureBoot authentication and for any BitLocker storage access, but not for the drivers certificate authentication or any other certificate.

That missing certificate is *possibly* just a certificate with which AMD signs, or signed, certain parts of their BIOS that are accessed by the SecureBoot process at boot. But if your PC already starts successfully, it may not be needed.

My suggestion would be to ignore the message in the event viewer, AMD or Microsoft will fix it at a certain point. Note that this message only appears if you installed/upgraded Windows 11 from a previous Windows 10 installation, it does not appear if you installed Windows 11 on a fresh partition by booting from a usb or dvd copy of the installation disk.

I tried exactly that and my problems still persisted, computer still freezed now and again. But, my freezing might not have had anything to do with that, even though the event was logged just before the freezing occured so I´m prety sure they were contected.

And in my case I didnt do an upgrade from win 10. I built a brand new machine with a new nvem-drive and installed win 11 from an usb-stick

There is no chance that after correctly disabling the task "AikCertEnrollTask" that specific event viewer message still appears. Your problem may be something else.

Sorry, I wasnt clear after disabling the task (and it was done properly) the error didnt appear again, even though another error occured instead (cant remember what that one was though). What did persist was the freezing. What I meant was that before I disabled the task the error came just before the computer freezed so in my world the two were conected.

The fact is, that many if not all owners of the current AMD line up do suffer on Windows 11 with random freezes and this particular error message. And the worst thing is, that no one either from AMD or MS do care about this.

But finally this is not the right place to post this as this is not something that ASUS can fix. For me personally this is broken and if this remains I'll switch back to Intel... they are not perfect but I can't remember that they failed on such easy tasks like certificate exchange and random freezes.

AMD should approach MS and fix this asap. MS doesn't have to move and Intel just smileys.. and even there is a fix in the pipe... this here is an emergency fix and not tbd sometime fix.

Every single component is my PC is less than four months old. The PCIe M.2 WD 1TB drive came from the packet and had Windows 11 Pro installed. This message appears with clean installations as well.
