When installing Windows Server 2003 intermediate and issuing CAs, you can request the CA certificate from an online CA, or you can save the certificate request to a request file and make the certificate request offline. If you make an offline CA certificate request, the CA is not valid immediately upon installation. You must use the Certification Authority MMC snap-in to import the certificate of the CA and complete the installation process after the parent CA signs the CA certificate. You can also use the Certification Authority MMC snap-in to import subordinate CA certificates that are issued by third-party parent CAs.
