不确定删除是否安全。我读到这些 AD 域名记录是由 netlogon 服务和/或其他服务创建的，并且不可更改。我有两个域控制器，每个都在 AD DNS 中正确显示，但有第三个记录，其 IP 为 192.168.203.0 ??? 我不知道它是从哪里来的。删除是否安全？
我之所以问这个问题，是因为这似乎在内部导致了 Exchange Autodiscover 的一些问题。dcdiag（无参数）返回所有正常，并且事件日志中没有关于复制或 AD 的错误。如果我使用 /test:dns 运行 dcdiag，我会得到各种错误，网络上的所有主机都被测试为 DC。
简单介绍一下背景。我们目前正在将 Exchange 服务器从 2003 迁移到 2010，并设置了新的 2012 R2 DC。旧 DC 是 Exchange 的 03。（我知道，这不好，但它是 10 年前由其他人设置的！）。我有一个使用相同服务器的实验室（来自迁移前拍摄的图像），并且域根目录中没有带有 .0 的 IP。因此，自从最近开始升级以来，这个问题就出现在生产系统中。03 服务器将在下周左右退役，所以也许它会在此过程中消失？
我很感激任何建议。谢谢！
这是域上的 nslookup，供参考，您可以看到 .0 记录。

如果您愿意，我可以提供标准 dcdiag 输出，但这里是 /test:dns 输出，只是一个片段（很长）。所有测试都通过了标准 dcdiag。但使用 test:dns，它会遍历网络上的所有 IP，甚至不显示实际 DC 的测试，当然它们都会失败。
