  • The role configuration fails with the following error message:
The Certificate Enrollment Web Service Setup failed because the CA "CA02.intra.adcslabor.de\ADCS Labor Issuing CA 1" cannot be contacted. Check the name, and confirm that the CA is properly configured and available. The RPC server is unavailable. 0x800706ba (WIN32: 1722 RPC_SERVER_UNAVAILABLE)   

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)„.
