| Event text (German): | The version or configuration identifiers of the certification authority "%1" cannot be read by the Certificate Registration Web Service.

Parameter
The parameters contained in the event text are filled with the following fields:
- %1: CAConfig (win:UnicodeString)
The Certificate Enrollment Web Services (Certificate Enrollment Policy Web Service, CEP, and Certificate Enrollment Web Service, CES) enable the automatic request and renewal of certificates from a certification authority via a Web-based interface. This eliminates the need to contact the certification authority directly via Remote Procedure Call (RPC). For a more detailed description, see the article "Certificate request basics via Certificate Enrollment Web Services (CEP, CES)„.
Example events
The Certificate Enrollment Web Service cannot read the version or the configuration flags from certification authority (CA) "CA02.intra.adcslabor.de\ADCS Labor Issuing CA 1." On the Security tab of the CA property sheet, grant Read permission to the account used by the Certificate Enrollment Web Service application pool. If no action is taken, subsequent requests will be rejected.
Description
The event is logged only once, further failed attempts of the same type are not logged again.
The event occurs when Key Based Renewal is used and the account under which the IIS application pool (WSEnrollmentServer) is running does not have read permission on the certificate authority.
Clients will see the error code WS_E_ENDPOINT_FAULT_RECEIVED when they attempt a Key based Renewal.
After correcting the permissions, the IIS application pool or the entire web server service should be restarted.
