各位大神，帮帮忙啊，以下是环境描述及问题，跪谢！
环境：
域环境：域名contoso.com 两台域控DC01和DC02，两个站点分别为site1（北京）和site2（上海），其中DC01属于site1，dc02属于site2
exchange 2010高可用环境：两台mailbox服务器（MBX01、MBX02）和两台CAS+HUB服务器（CAS01、CAS02），MBX01和CAS01在站点site2下IP地址段为192.68.1.0/24段，MBX02和CAS02在站点site1下，IP地址网段为172.17.1.0/24.两台mailbox心跳地址分别为MBX01：1.1.1.2/24，MBX02：2.2.2.2/24，
网络环境：网络上无任何端口限制，无防火墙，无杀毒软件
问题：两台mailbox做
DAG，可以添加任何一台到DAG中，无法添加第二台到DAG中，使用
控制台添加时，如下图，无报错，进度条不走，一直那样直到15分钟后报以下错误，同样尝试过使用命令在EMS中添加，使用命令在
powershell中添加节点，通过故障转移群集添加节点均不行！！！
以下为日志文件：
