Details of CA: CA的详细信息:
Now, I have developed a sample .Net WebAPI application which should send a CSR request to my CA and CA should return the signed certificate to the requester.现在,我开发了一个示例 .Net WebAPI 应用程序,它应该向我的 CA 发送 CSR 请求,并且 CA 应该将签名证书返回给请求者。 This application is hosted as a web app on IIS on the same EC2 instance.
此应用程序作为 Web 应用程序托管在同一 EC2 实例上的 IIS 上。

Problem(s):问题):
when " Cavium Key Storage Provider " or " RSA#Cavium Key Storage Provide r" is used to initialize objCSP, " Invalid provider specified.

To resolve the "The RPC server is unavailable" issue, I have followed the steps https://itworldjd.wordpress.com/2015/10/21/pki-certificates-troubleshooting-certificate-enrollment-rpc-server-is-unavailable/ but no luck.为了解决“RPC服务器不可用”问题,我按照步骤https://itworldjd.wordpress.com/2015/10/21/pki-certificates-troubleshooting-certificate-enrollment-rpc-server-is-unavailable /但没有运气。
I hit this error too.我也遇到了这个错误。 Hopefully someone can benefit from how I addressed it.
希望有人可以从我如何解决它中受益。
After requesting a new cert over web enrollment I also got the error.通过网络注册请求新证书后,我也收到了错误消息。
CCertRequest::Submit: The RPC server is unavailable. CCertRequest::Submit:RPC 服务器不可用。 0x800706ba (WIN32: 1722 RPC_S_SERVER_UNAVAILABLE)
0x800706ba (WIN32: 1722 RPC_S_SERVER_UNAVAILABLE)
Without going into all the detail of DCOM permissions you need to ensure you are accessing the Certificate web server remotely and not locally from the CA server.无需深入了解 DCOM 权限的所有细节,您需要确保远程访问证书 Web 服务器,而不是从 CA 服务器本地访问。
