Azure虚拟桌面专题之十一：解决DomainTrustCheck失败导致会话主机状态不可用问题

在创建完主机池并添加会话主机之后，在主机池概述中发现虚拟机总数和不可用状态数量一样，也就是说所有的虚拟机状态都处于不可用

刚开始创建之后的几分钟内状态不可用是正常现象，一般等等几分钟之后就会变为可用。可这次发现等了很长时间还是不可用，这就有问题了。

到底是什么原因导致状态不正常呢。选择其中一台虚拟机，进入查看详细信息

发现是DomainTrustCheck、DomainJoinedCheck 检查不通过，疑难解答信息为：“此健康状况检查验证会话主机是否已加入域。如果此检查失败，则将是致命的，并且不会成功连接。要解决此问题，请将该虚拟机加入域。”

查看JSON文件，

从以上信息可以判断出应该是虚机没有加域导致的。那么我们只要把虚机加入Azure AD后，应该就能解决此问题了。

解决方案：使用管理员登录虚拟机，进入计算机设置，可以在搜索中输入settings 进入计算机设置，找到Account，在Account中有个Add work or school account ,点击进入后在弹出的对话框中输入Azure AD的用户名和密码，确认后点击join 以将虚拟机加入Azure AD。

回到会话主机概述页面，点击刷新

此时虚拟机状态已变为可用，至此问题解决
