今天CRM 服务器挂了，具体现象为在浏览器中打开CRM Organization时无法打开，创建CRM Organization和导入CRM Organization是出错，打开日志文件，发现错误信息如下：
23:44:34| Error| Create new Organization (Name=5fe4dd0e-1f7f-e211-a4a4-00155d8a1700, Id=DeployDemoShow) failed with Exception: System.Exception: Action Microsoft.Crm.Tools.Admin.ProvisionBusinessAction failed. ---> System.Runtime.InteropServices.COMException: The server is not operational.

查看错误堆栈发现这是访问域服务器时出错，回忆起之前CRM Organization Manager无法打开的那次（大家可参考http://support.microsoft.com/kb/954811），猜测是Logonserver变掉了，在命令行执行"echo %logonserver%"发现确实如此，更新注册表键值PreferredDc之后重新打开CRM Organization Manager，重新导入Organization，成功！
