Last night I was working on a project involving Windows Server 2008. I needed to request Computer certificate from an Enterprise Certificate Authority that was a member of the same domain as the server that I was working on. When I went to make the request though, the Certificates console told me that there were no available Certificate Templates. The problem was a matter of trust. The server had not been issued a root certificate, so it did not trust my certificate authority. This prevented the server from being able to issue certificate requests. Once I downloaded and installed the root certificate, the problem went away.
