Intel PTT AIK Enrollment Fails, Microsoft AIK Authority Does Not Exist, HTTP 404

Question

I am experiencing a TPM AIK enrollment failure on Windows 11 with an Intel Core Ultra 7 265F and Intel PTT 2.0.

TPM 2.0 is enabled, ready and functional. Secure Boot is enabled and active. Windows TPM diagnostics reports the machine as attestable.

I identified and repaired an incomplete local Intel EK certificate chain using the Intel intermediate certificates stored in my own TPM NV storage. After repair:

TpmDiagnostics.exe ekchain

now reports:

Trust dwErrorStatus: 0x10000

However, AIK enrollment still fails when running:

certreq -enrollaik -config ""

Microsoft now returns:

HTTP 404 Not Found

0x80190194 / HTTP_E_STATUS_NOT_FOUND

Server response:

The authority "intc-keyid-<PII removed>.microsoftaik.azure.net" does not exist.

Intel PTT KeyId:

TPM Manufacturer: Intel (INTC) TPM Model: MTP CPU: Intel Core Ultra 7 265F Motherboard: ASRock B860M-C BIOS: 3.31 Windows 11 Home 64-bit, build 26200.9168

The failure occurs during GetCACaps, before an AIK enrollment request is submitted.

Microsoft request ID:

<PII removed>

This is affecting Call of Duty Secure Attestation because Windows cannot obtain a Windows AIK certificate despite the TPM EK certificate chain now validating successfully.

Please escalate this to the team responsible for Microsoft AIK/Azure TPM attestation infrastructure. Can you confirm whether this Intel PTT KeyId/authority needs to be provisioned or onboarded in the Microsoft AIK service?

Hello billy chavez,

Welcome to Microsoft Q&A forum.

You are not alone in this, actually I have seen other users reporting this issue recently. Based on some check, this is highly likely something that need to be done on the server side. This is just a public forum so engineering team might not check it very often. You can escalate this to them directly using the Feedback Hub app on your Windows computer. Also, as I know a few users have already submitted it so you can go and check.

Thank you for your understanding.
