复制域控制器时，“RPC服务器不可用”

我有两个域控制器：

DC1：Win2k3 R2 EGDC1：Win2k8 R2

当我尝试复制这两个（通过Manage Sites and Services并在NTDS Settings ）通过selectReplicate Now ，我收到错误消息The RPC Server is unavailable 。 如果我在遥控DC1或DC2的情况下尝试此操作并不重要。

根据这个technet文章 ，这是一个机器被closures的问题。 不过，我可以另外有两个域控制器相互ping通，所以没有DNS问题，也没有任何连接问题。 两者都在同一局域网上，甚至在同一个子网上，所以没有像这样的VPN / WIFI /防火墙/古怪的问题应该是一个问题。

• 从另一台虚拟机ping VM
• 在不同的目标域上运行`certutil -DCInfo`
• 使用Samba PDC，域pipe理员在Windows Server 2008上没有pipe理权限
• 在域控制器上超出会话限制？
• gpsvc消耗ldap端口？

另外，我validation了RPC服务在两个盒子上运行。

有什么问题可以解决吗？
