PAC 验证失败

PAC_Verification_Failure_5_Rule (Rule)

Knowledge Base article:

摘要

Kerberos 验证来自密钥分发中心 (KDC) 的 Kerberos 票证中的特权属性证书 (PAC) 字段上的签名时失败。这表示 PAC 字段已被修改。

这很重要,因为 PAC 字段是用来存储用户令牌的字段。可能有人试图侵入您的系统。

也有可能是路由器上的内存问题导致在传输过程中损坏了数据包,但这种情况比较少见。

解决方案

验证票证授予服务 (TGS) 回复数据包是否来自 KDC。如果不是,请调查是否有人试图侵入您的系统。

如果数据包不是来自 KDC,请重新设置 KDC 的计算机帐户密码。
