無法取得 Kerberos 伺服器的 ISAKMP/ERROR_IPSEC_IKE 服務認證，Kerberos 將不會進行驗證功能。最可能的造成原因是缺少網域成員資格。如果您的電腦是工作群組成員，這就是正常現象。

Failed to obtain Kerberos server credentials for ISAKMP/ERROR_IPSEC_IKE service. Kerberos authentication will not function. The most likely reason for this is lack of domain membership. This is normal if your computer is a member of a workgroup.
