Windows身份验证适用于某些但不适用于其他人

我有一个通过IIS托管的Web应用程序,需要Windows身份验证。一些用户可以毫无问题地访问应用程序。其他人得到一个请求凭据的对话框,但当他们取消请求时,应用程序正确加载。还有一些提示输入凭据,当他们输入凭据时,会收到401错误。使用Fiddler,我发现有效用户的身份验证标头如下所示:

提示输入凭据(但应用程序仍加载)的用户如下所示:

标题看起来非常相似,但是对于不起作用的情况,缺少以下标志:

  • 签署(诚信)
  • 客户端将在类型3会话密钥字段
  • 中提供主密钥

我一直在谷歌搜索几天,我似乎无法确定这些密钥的来源!这与浏览器设置有关吗?帐户设置? IIS设置?

非常感谢任何建议!
