Description
For this event, special attention should be paid to the error code entered in the event text (parameter %2, ErrorCode):
Error code CERTSRV_E_BAD_REQUESTSTATUS
This error occurs when a certificate request Key based Renewal is attempted but the EDITF_ENABLERENEWONBEHALFOF flag is not set on the certificate authority.
Error code CERTSRV_E_BAD_REQUESTSUBJECT
This error occurs when the certificate authority cannot verify the subject part of an incoming certificate request. See also the article "Certificate request fails with error message ".Error Parsing Request The request subject name is invalid or too long. 0x80094001 (-2146877439 CERTSRV_E_BAD_REQUESTSUBJECT)"„.
- As can be seen in the example event, the applicant's identity was accidentally entered in Country (C) rather than in the Common Name (CN) RDN. The Country field but allows only two digits (optimally the one after ISO 3166 defined country codes), so that the certificate request could not be processed by the certification authority and was therefore rejected.
- There was a unauthorized Relative Distinguisghed Name (RDN) in the subject of the certificate request.
- The Applicant (Subject) field in the certificate request is identical to that of the certification authority.
- An RDN requested in the Applicant (Subject) field (e.g. Common Name) is longer than allowed. See also article Certificate request fails with error message "Error Parsing Request The request subject name is invalid or too long. 0x80094001 (-2146877439 CERTSRV_E_BAD_REQUESTSUBJECT)"..
Error code ERROR_INVALID_PARAMETER
This error can occur when a Windows 10 client tries to obtain a certificate with Trusted Platform Module (TPM) key attestation from a Windows Server 2012 R2 certificate authority. The error was fixed with KB3154769, which is available in the June 2016 update rollup for Windows RT 8.1, Windows 8.1 and Windows Server 2012 R2 is included.
Error code CERTSRV_E_NO_VALID_KRA
Error code ERROR_FILE_NOT_FOUND
See article "Certificate request fails with error message "The system cannot find the file specified. 0x80070002 (WIN32: 2 ERROR_FILE_NOT_FOUND)".„.
Error code CERT_E_UNTRUSTEDCA
Error code CRYPT_E_NO_REVOCATION_CHECK
Occurs when the revocation status of the certification authority certificate cannot be checked, e.g. because the revocation list is not available or has expired.
Occurs when the autoenrollment permission is set on a certificate template for OCSP password signing and thus certificate requests are signed with an OCSP password signing certificate. Revocation status checking is then not possible because these certificates do not contain revocation status information. See article "Certificate requests for the online responder (OCSP) fail sporadically with error message "The revocation function was unable to check revocation for the certificate. 0x80092012 (-2146885614 CRYPT_E_NO_REVOCATION_CHECK)"„.
Error code CRYPT_E_ASN1_BADTAG
Occurs when the submitted certificate request could not be processed, i.e. most likely invalid data was sent to the certification authority instead of a certificate request.
Error code CRYPT_E_ASN1_EOD
See error code CRYPT_E_ASN1_BADTAG.
Error code ERROR_ACCESS_DENIED
Occurs, for example, when a certificate is to be retrieved that was not requested by the requesting account. This can indicate an attack attempt and, if it occurs more frequently, should possibly be alerted.
Safety assessment
The security assessment is based on the three dimensions of confidentiality, integrity and availability.
