I have a Windows Server 2008 Enterprise Root CA with a different Windows 2008 Server running the Cert Enrollment website (ussing SSL). Any certificate that I attempt to request (Vista or XP) results in:============================================ 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.=================================The Windows Firewall is off between the web enrollment server and the CA, but only 443 is open in to the web enrollment server from externally.What am I missing here? This is rapidly becoming a showstopper.Thanks,BH

I'm having a slightly related problem. I have Certificate Services running on a Windows 2008 Enterprise Edition 64-bit. I installed it as aEnterprise subordinate CA, using a certificate from the original enterprise CA. It is set up as I am trying to enroll a certificate on another computer. When I use "Automatically Enroll and Retrieve Certificates", I see the certificate I want. However, when I try to enroll it I get the following error:The RPC server is unavailable.The certificate rquest could not be submitted to teh certificate authorityThere are no firewalls between the certificate authority and I tried using the certutil ping command as stated above and I got an 'is alive' reply from the CA.Any idea what my hang up could be?

I having the same issue. Were you able to reslove it. certutil -ping -config "ca.example.com\Example Corporation Corporate CA" is alive. any Suggestions
