SYMPTOMS
Consider the following scenario:
 * A Windows Server 2003-based computer hosts an enterprise certification authority (CA).
 * The enterprise CA issues certificates by using a customized certificate template.
 * The certificate template is configured to include the user principal name (UPN) or the service principal name (SPN) in the alternate subject name.

In this scenario, all certificates that are issued by using the customized certificate template have incorrect alternate subject names. The alternate subject name is a Domain Name System (DNS) name instead of a UPN or an SPN.

This problem prevents the enterprise CA from issuing Network Access Protection (NAP)-compliant computer certificates.
