WEB 页面需要第二次尝试才​​能加载 - DNS 问题

我遇到了这个从未遇到过的问题,想向社区寻求帮助。

我想我可能遗漏了或者忽略了一些小细节。我遇到的问题是,当我尝试访问外部网站时,第一次通常会出错,但第二次会成功。例如,如果我尝试从 Chrome 访问 Cisco,第一次会出错并显示“我未连接到互联网”或尝试返回页面的缓存版本。第二次会正确返回网页。我尝试访问的所有互联网/外部网站都会发生这种情况。

我进行了跟踪路由,以查看我的网络在哪里丢弃了通信,看起来所有东西都被路由回我的 IP。我从未见过这种情况,所以任何帮助都将不胜感激。我附上了我的 tracert 的屏幕截图。它确实命中了一次不在我的网络中的 209.xxx......这也令人困惑。

更多背景信息,我在同一台机器上有两个虚拟机,没有这个问题,它只影响主机。我在企业网络上,我是唯一一个遇到这个问题的人

Tracert(csc2-pc 是我的计算机)

所以我搞明白了。这是 DHCP/防火墙上的错误设置,其中一个电路发出了错误的 DNS 服务器。谢谢大家 – MannyFresh 5 月 2 日 22:42
