WIN 2012 DNS 问题

WIN 2012 DNS 问题

我正在排除森林中主 DC 上的 DNS 服务器问题。我在尝试启动并运行第二个控制器时遇到了这个问题。

dcdiag /test:dns 的当前结果如下

     ......................... domain.com failed test DNS

因此,我一直在尝试排除 Basc 错误可能是什么原因,但目前我还不确定,而且任何搜索都无果而终。

我很高兴提供更多信息或诊断输出。

答案1

您在服务器的 TCP/IP 设置中将 127.0.0.1 列为唯一的 DNS 服务器。DCPROMO 进程确实会进行该设置,但如果将 127.0.0.1 配置为第一个 DNS 服务器,BPA 将生成警告。将服务器的实际 IP 地址设置为主 DNS,并将 127.0.0.1 设置为辅助 DNS,然后重新启动服务器并再次检查

答案2

我看到这个问题已经得到解答了,但我想跟进一下。这是一个最佳实践问题。运行 DNS 的 BPA,您会发现不再建议将环回地址作为第一个 DNS 服务器。在单个 DNS 服务器环境中,服务器的 IP 应该是主服务器,然后如果您愿意,您可以将环回地址放在辅助插槽中。

不过,这实际上是 BPA 旨在解决的问题。部署完 AD 后,您应该运行 DNS 和 AD BPA。通过尽早且频繁地运行 BPA(在配置更改、添加新服务器等之后),可以避免许多奇怪且难以排除故障/追踪的问题。
