DNS 问题？目前没有可用的登录服务器

尽管我已阅读了大量包含相同错误消息的帖子，但我仍无法找到适合我的情况的解决方案。

我有一台 Windows 2008 服务器，大约一年前我重建了它，当时我还没有意识到重建会带来什么后果。我没有正确地将其从域中删除。我的目标是为 C:\ 驱动器添加更多空间，以及升级处理器和 RAM，以便我可以开始使用 Hyper-V。长话短说，我从家里带来了一台运行 Windows Server 2012 的个人服务器。我在重建主服务器时使用它来支持域。因此，所有角色都暂时由我的个人服务器提供。

我重建了 2008 服务器并重新移动角色，这就是我的问题开始的地方。当我降级 2012 服务器并将其脱机时，我的所有客户端都会收到臭名昭著的“当前没有可用的登录服务器...”。我将 2012 服务器重新联机，将其升级回 DC，问题不再存在。我甚至不必降级/升级即可出现问题；只需关闭它，问题就会再次出现。

说实话，我厌倦了我的个人服务器每天整天在我耳边嗡嗡作响（我还想把它带回家，因为它是个人服务器）。我只是不知道如何在不关闭整个网络的情况下将其从域中移除。

林和域功能级别仍为 2008。'netdom query fsmo' 返回指向 2008 服务器而不是 2012 服务器的所有角色。

2008 server roles:
    AD DS
    DHCP
    DNS
    File Services
    Hyper-V
2012 server roles:
    AD DS
    DHCP (service is stopped)
    DNS
    File Services

我正在寻求建议，看看我还可以尝试哪些其他方法成功解决此问题，而这些建议可能比我在这方面的知识丰富得多。我花了无数个小时在谷歌上搜索并尝试了各种方法。我不记得我都尝试了什么，因为我已经与此作斗争了大约一年。任何建议/指导都将不胜感激。如果需要，我绝对可以回发查询的输出。
