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 list of available certificate templates within the MMC is completely empty.
In the list of available certificate templates within the MMC, all certificate templates are displayed. At all desired certificate templates it is written:

Cannot find Object or property.
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.

Installing a Certificate Enrollment Policy Web Service (CEP)

The following describes how to install the Certificate Enrollment Policy Web Service (CEP).

Configure the Certificate Enrollment Policy Web Service (CEP) to work with a domain account.

The following describes how to set up a Certificate Enrollment Policy Web Service (CEP) that the service runs under a domain account.

Configure the Certificate Enrollment Policy Web Service (CEP) to work with a Group Managed Service Account (gMSA).

For security reasons, it may make sense to operate the CEP with a Group Managed Service Account (gMSA) instead of a normal domain account. This option offers the charming advantage that the password of the account is changed automatically, and thus this step does not have to be done manually, which is unfortunately forgotten far too often.

View and clear the certificate enrollment policy cache for the Certificate Enrollment Policy Web Service (CEP).

After a certificate enrollment policy is configured and used by a subscriber, the results are cached locally (Enrollment Policy Cache).

If changes are now made to the infrastructure, for example by publishing or removing a new certificate template on a certification authority accessible via Certificate Enrollment Web Service (CES), these changes are not immediately visible to subscribers due to the cache.

For this reason, it may be helpful to view or clear the cache.

The creation of a certificate enrollment policy for the Certificate Enrollment Policy Web Service (CEP) fails with the error message "This ID conflicts with an existing ID."
