You try to enroll a certificate from a certificate enrollment Web page.
The certificate that you receive from the certification authority is an unsigned PKCS7 response.
The certificate chain for the new certificate cannot be built, or the chain validation fails.
To install the end entity certificate on a client computer, the certificate enrollment Web page uses the InstallResponse method of the IX509Enrollment interface of the CertEnroll COM object.
In this scenario, when you use Windows Internet Explorer 7 to open the certificate enrollment Web page and to install the end entity certificate on a Windows Vista-based client computer, the installation may fail.Additionally, you may receive one of the following error messages from the InstallResponse method of the IX509Enrollment interface:
Error Code: E_ACCESSDENIED 0x80070005L Error Message: "General access denied error" This error occurs if the certificate response is installed using a InstallResponseRestrictionFlags such as AllowUntrustedRoot other than AllowNone.
Error Code: CERT_E_CHAINING 0x800B010AL Error Message: "A certificate chain could not be built to a trusted root authority" This error occurs if the certificate chain response contains an end entity certificate but not the complete certificate chain to a root CA.
Error Code: CERT_E_UNTRUSTEDROOT 0x800B0109L Error Message: "A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider" This error occurs if the certificate chain response is containing the leaf end entity certificate chaining to an untrusted root CA.
