恢复 2 个 DC 后，网络被检测为公共网络且 DcDiag 失败

Question

我有一个（小型）域，其中有 2 个运行 Windows 2012 R2 的（虚拟化）DC。

为了测试目的，我在与生产环境隔离的实验室环境中恢复了它们。该实验室环境使用相同的 IP 地址范围、相同的网关 IP 并可以访问互联网 - 但与生产环境隔离。

当我重新启动 2DC 时，网络类型未检测到域。因此我进行了一些搜索，还看到 dcdiag 报告错误（见下文）另一方面，名称解析和 ping 正常

由于Hypervisor与原先不同，NIC被视为一个新设备。但每个DC上仍然只有一个NIC。

有什么建议吗？

先感谢您。
