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)
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)„.
Possible causes can be:
- The CES server cannot be resolved via the Domain Name System (DNS).
- This can also happen if the address of the CES was entered or stored incorrectly.
