Assume the following scenario:
- A user requests a certificate.
- An enrollment policy is configured for this, which points to a Certificate Enrollment Policy Web Service (CEP).
- The connection to the CEP fails and the user receives the following error message:
Error: The operation timed out 0x80072ee2 (WinHttp: 12002 ERROR_WINHTTP_TIMEOUT)
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)„.
This error message indicates that the CEP cannot be reached by the requester. This may be due to the following reasons:
- The CEP server is offline.
- The network connection to the CEP server is silently dropped by a firewall.
