SYMPTOMS

You apply hotfix 943089 on a Windows Server 2003-based server that hosts Certificate Services. After you do this, the subject name of a computer certificate that is issued by this server is set to the user principal name (UPN) of the computer account for which the certificate is issued.

Before you apply hotfix 943089, the subject name of the computer certificate that is issued by a Microsoft certification authority (CA) server is built from the DNS name of the computer account.

Because of this change, applications that expect the subject name of the certificate to contain the DNS name of the computer account may become unable to use a certificate that is created in the new format.

CAUSE

This change is introduced by hotfix 943089. This hotfix was released to resolve an issue in which the Subject Alt Name (SAN) field of the issued certificate contains the DNS name instead of the UPN of the computer account for which the certificate is issued.

RESOLUTION

To restore the pre-hotfix 943089 method of building the subject name from the DNS name of the computer account, apply hotfix 961515 on the Windows Server 2003-based server that hosts Certificate Services.
