Advanced queries against the certification authority database

The Certification Authority database stores much of the information about a Certification Authority's activities. Among other things, it contains information about:

Certificates issued
Revoked certificates
Published blacklists
Pending certificate requirements
Rejected certificate requests
Failed certificate requests

Viewing the contents of the certification authority database is usually done via the certification authority's management console (certsrv.msc), but the possibilities for evaluation and especially for machine processing are very limited.

Requesting a certificate for domain controller fails with error message "The RPC server is unavailable. 0x800706ba (WIN32: 1722 RPC_SERVER_UNAVAILABLE)".

Here's the scenario:

Requesting a certificate for a domain controller fails.
The certificate request is logged in the failed requests section of the certification authority. The error message reads:

The RPC server is unavailable. 0x800706ba (WIN32: 1722 RPC_S_SERVER_UNAVAILABLE)

Requesting a certificate fails with the error message "A valid certification authority (CA) configured to issue certificates based on this template cannot be located, or the CA does not support this operation, or the CA is not trusted."

Assume the following scenario:

You try to apply for a certificate from an Active Directory-integrated certification authority (Enterprise Certification Authority).
To do this, use the Microsoft Management Console (MMC), either for the logged-in user (certmgr.msc) or for the computer (certlm.msc).
However, the desired certificate template is not displayed for selection, even though it has been correctly published on the certification authority.
The logged-in user (or computer) also has the necessary permissions to request certificates from the certificate template in question (enroll).
In the list of available certificate templates within the MMC, all certificate templates are displayed. At the desired certificate template is written:

A valid certification authority (CA) configured to issue certificates based on this template cannot be located, or the CA does not support this operation, or the CA is not trusted.
