hi, I want to request for certificate programmatically from a certificate server and install the received certificate. I have set up a certificate server as per http://bizsecurity.about.com/od/internetsecurity/a/certificate.htm. When i use the msdn example for requesting the certificate, it shows an "rpc server not available" error. But i can request for certificate by manuall going to http://servername/certsrv. it does not give me any error. Only when i try to do it programmatically it shows me an error. Can anyone please assist me in solving this problem? Also can i set up the server to issue a specific type of certificate? Thanks in advance..
