Description

Occurs when the certification authority cannot determine whether it is authorized to issue customized certificate templates.

Up to Windows Server 2008 R2 there was a distinction whether one had installed the "Standard Edition" or the "Enterprise Edition" (for Windows 2000: Advanced Server) of the operating system. Only if the certificate authority was installed on the "Enterprise Edition" of the operating system could you use your own certificate templates.

See article "After installing or migrating a certificate authority to a new server, you can no longer publish your own certificate templates" for more information.
