SCEP Certificate enrollment initialization is failing on my new hardware, Intel Core Ultra 7 270k plus with Gigabyte z890 Eagle Wifi7 Plus, on Windows 10 Pro. Here is the complete application error event: SCEP Certificate enrollment initialization for Local system via https://INTC-KeyId-6be80519dd622d1b7c93705afb7a096085fbf983.microsoftaik.azure.net/templates/Aik/scep failed: GetCACaps GetCACaps: Not Found {"Message":"The authority "intc-keyid-6be80519dd622d1b7c93705afb7a096085fbf983.microsoftaik.azure.net" does not exist."} HTTP/1.1 404 Not Found Date: Fri, 04 Sep 2026 10:09:09 GMT Content-Length: 122 Content-Type: application/json; charset=utf-8 X-Content-Type-Options: nosniff Strict-Transport-Security: max-age=31536000;includeSubDomains x-ms-request-id: 418748de-8930-4a42-a26c-a4f1df841331 Method: GET(3875ms) Stage: GetCACaps Not found (404). 0x80190194 (-2145844844 HTTP_E_STATUS_NOT_FOUND) Thanks in advance for any help you could offer in onboarding the missing keys to the azure infrastructure.
The 404 is the part I would focus on first. It looks less like a problem with the Z890 board itself and more like the SCEP endpoint/AIK enrollment service being unavailable or the authority in the generated URL no longer existing.
Since the error is specifically:
GetCACaps: Not Found The authority "...microsoftaik.azure.net" does not exist.
I’d check Windows Update and the Intel/Gigabyte firmware and chipset/ME drivers first, then reboot and see whether the SCEP enrollment retries successfully.
If the same 404 persists after that, I wouldn't keep changing BIOS settings blindly. The endpoint is returning an actual HTTP 404, so it may need to be resolved on Microsoft's AIK/SCEP infrastructure side rather than locally.
If you can share the relevant TPM/Device Management event entries around the same timestamp, that could help determine whether the AIK provisioning itself is failing or whether Windows is simply reaching a stale/invalid SCEP authority.
