一个域名
两个域控制器(2008)
一个是有道德的
一个是物理的
同一个网站
域控制器之间的ping是好的.

好吧,基本上我必须对托管虚拟机的服务器进行BIOS升级(域控制器是其中一个虚拟机).更新后,我们的cisco交换机出现问题,因为智能端口已启用,并且在所有虚拟机和包含所有其他物理机的物理网络之间停止流量.

现在我们通过禁用2960上的智能端口来修复此问题,并且所有虚拟机都可以与物理机成功通信,一切正常.
然而;当我们为域控制器启动VM时,启动花了很长时间(我知道AD / DNS问题很常见).当它最终启动时我登录并立即尝试ping第二个DC. ping响应很好,一切都很好网络明智.但突然之间域控制器没有同步.我尝试了repadmin / syncall并且出现了错误,我尝试了dcdiag / q并且我也遇到了错误.
RPC服务无法与FSMO持有者通信(简而言之).

我查了一下,dfsr服务运行正常.我切换了任何防火墙和防病毒软件,除了ping之外,他们仍然无法通信.什么都没有改变？

有人能指出我在哪里开始正确的方向吗？
出于测试目的,我在第二个DC上创建了一个对象,它没有复制到第一个DC(FSMO持有者).
