Certificate Enrollment Web Service (CES) - Page 2

Classification of ADCS components in the Administrative Tiering Model

If, in addition to the Active Directory Certificate Services, the administrative tiering model is also implemented for the Active Directory directory service, the question arises as to how the individual PKI components are to be assigned to this model in order to be able to perform targeted security hardening.

Certificate Enrollment Web Service (CES) request fails with error code "WS_E_ENDPOINT_FAULT_RECEIVED".

Assume the following scenario:

A Certificate Enrollment Web Service (CES) is implemented in the network.
A certificate request is sent to the CES.
The certificate request fails with the following error message:

A message containing a fault was received from the remote endpoint. 0x803d0013 (-2143485933 WS_E_ENDPOINT_FAULT_RECEIVED)

Required Windows security permissions for the Certificate Enrollment Web Service (CES)

Assuming one implements Microsoft's Active Directory Administrative Tiering Model, or applies similar hardening measures to one's servers, this will impact the CES components.

Required firewall rules for the Certificate Enrollment Web Service (CES)

Implementing a Certificate Enrollment Web Service (CES) often requires planning the firewall rules to be created on the network. The following is a list of the required firewall rules and any pitfalls.

The operation fails with the following error message:

The remote endpoint was not reachable. 0x803d0010 (-2143485936 WS_E_ENDPOINT_UNREACHABLE)

Requesting certificates via Certificate Enrollment Web Service (CES) fails with error code "ERROR_WINHTTP_CANNOT_CONNECT".

Assume the following scenario:

You try to request a certificate via a Certificate Enrollment Web Service (CEP) from an Active Directory-integrated certification authority (Enterprise Certification Authority).
The operation fails with the following error message:

Certificate Request Processor: A connection with the server could not be established 0x80072efd (WinHttp: 12029 ERROR_WINHTTP_CANNOT_CONNECT)

Requesting certificates via Certificate Enrollment Web Service (CES) fails with error code "ERROR_WINHTTP_TIMEOUT".

Assume the following scenario:

You try to request a certificate via a Certificate Enrollment Web Service (CEP) from an Active Directory-integrated certification authority (Enterprise Certification Authority).
The operation fails with the following error message:

Certificate Request Processor: The operation timed out 0x80072ee2 (WinHttp: 12002 ERROR_WINHTTP_TIMEOUT)

Requesting certificates via Certificate Enrollment Web Service (CES) fails with error code "ERROR_WINHTTP_NAME_NOT_RESOLVED".

Assume the following scenario:

You try to request a certificate via a Certificate Enrollment Web Service (CEP) from an Active Directory-integrated certification authority (Enterprise Certification Authority).
The operation fails with the following error message:

Certificate Request Processor: The server name or address could not be resolved 0x80072ee7 (WinHttp: 12007 ERROR_WINHTTP_NAME_NOT_RESOLVED)

Requesting certificates via Certificate Enrollment Web Service (CES) fails with error code "ERROR_WINHTTP_INVALID_CA".

Assume the following scenario:

You try to request a certificate via a Certificate Enrollment Web Service (CEP) from an Active Directory-integrated certification authority (Enterprise Certification Authority).
The operation fails with the following error message:

The certificate authority is invalid or corrupt. 0x80072f0d (WinHttp: 12045 ERROR_WINHTTP_SECURE_INVALID_CA)

Requesting certificates via Certificate Enrollment Web Service (CES) fails with error code "WS_E_OPERATION_TIMED_OUT".

Assume the following scenario:

You try to request a certificate via a Certificate Enrollment Web Service (CEP) from an Active Directory-integrated certification authority (Enterprise Certification Authority).
The operation fails with the following error message:

Certificate Request Processor: The operation did not complete within the time allotted. 0x803d0006 (-2143485946 WS_E_OPERATION_TIMED_OUT)

Requesting certificates via the Certificate Enrollment Policy Web Service (CEP) fails with 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 request a certificate via a Certificate Enrollment Policy Web Service (CEP) 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 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.
