description: |
    Detects errors when a target server doesn't have suitable keys for generating kerberos tickets.
    This issue can occur for example when a service uses a user account or a computer account that is configured for only DES encryption on a computer that is running Windows 7 which has DES encryption for Kerberos authentication disabled.
