问题：
用户反馈重启数据库服务器的备节点后，数据库服务无法启动，提示下面的错误。
检查数据库的错误日志信息如下：

原因分析：
因为数据库搭建了always on高可用性组，所以数据库服务启动账号是使用域账号来管理的。尝试使用本地账号启动数据库服务，发现可以正常启动。
经查原因：
SQL启动域帐号的status=Temporary
Windows Server 2012位置：Control Panel --> system --> Advanced system settings --> Advanced --> User Profiles -->Settings
可以看到SQL Server服务的启动账号有两个Profiles文件，一个状态是Backup，一个是Temporary。正常情况应该是只有一个状态为local的文件。
正常情况应该是
解决方案：
方案一：
删除状态是Backup的profile文件，然后重新启动。
方案二：
1.SQL启动帐号改成local system.
2.退域重加域
之后再查启动帐号的status=Local
本次是使用方案一进行处理的，删除文件后重新登录操作系统跟刚加域后登录很相似。
