These certificates consist of root certificates, intermediate certificates, and leaf server certificates.

Intermediate certificates are certificates that are designed to mitigate risk by creating a separator between the root certificates and SSL certificates. On the Specify the type of the private key page, verify that Create a new private key is selected, and then click Next.

For more information on CA hierarchy planning, see the resources listed under the Plan section of the Windows PKI documentation reference and library. Furthermore, installing an offline CA on a server that is a member of a domain can cause problems with a secure channel when you bring the CA back online after a long offline period.

This is because the computer account password changes every 30 days. You can get around this by problem and better protect your CA by making it a member of a workgroup, instead of a domain. The following checklists are to provide assistance in creating a CA hierarchy with an offline root CA and online subordinate CA. On the new root CA, change the URL location of the certificate revocation list CRL distribution point to a location of your choice that is accessible to all users in you organization's network.

On the new root CA, change the URL location of the authority information access AIA distribution points to a location of your choice that is accessible to all users in you organization's network.

In Windows Explorer on the root CA, locate the certificate revocation list you just published. Right-click the CRL file and send it to a drive that has portable storage media.

Publish the root certificate to the enterprise root store and add the certificate to the customary Authority Information Access AIA points in the directory. You need to use certutil.
