Hello,
I get the following error when requesting an advanced certificate request from the certificate authority's web service: http://server.domain/certsrv/en-US/certrqus.asp. I'm doing the request on the certificate authority server (Windows Server 2008 R2) so it shouldn't be a firewall issue. There are no other roles installed to this server.
Your request failed. An error occurred while the server was processing your request.
Contact your administrator for further assistance.
Request Mode:newreq - New Request Disposition:(never set) Disposition message:(none) Result:The RPC server is unavailable. 0x800706ba (WIN32: 1722) COM Error Info:CCertRequest::Submit: The RPC server is unavailable. 0x800706ba (WIN32: 1722) LastStatus:The
operation completed successfully. 0x0 (WIN32: 0) Suggested Cause: This error can occur if the Certification Authority Service has not been started.
I have done some searching and still have not found the issue. User certificate request via web site works fine and the certificate service doesn't seem to have any problems (requests are accepted via other methods). I have also verified the following:
0x800706ba - The RPC server is unavailable
- Verify that the client can get a certificate using the Manual Enrollment via the MMC Certificate Wizard.
- Check network connectivity to all of the available certification authorities listed in the Enrollment Services object listed in the Active Directory:CN=Enrollment Services,CN=Public Key Services,CN=Services,CN=Configuration,DC=Domain,DC=com
- Verify that the Certificate Services service is running on the certification authority.
- Check for firewalls and proxy settings.
- Use Portqry to verify that the necessary RPC ports are opened.
Thanks for any help.
