现象：重启citrix服务器后，打开发布的相关程序，提示：

查看系统日志：事件类型: 错误 事件来源: Web Interface at c:\inetpub\wwwroot\Citrix\MetaFrame 事件种类: 无 事件 ID: 0 日期:  2010-04-17 事件:  10:51:11 用户:  N/A 计算机: CITRIX 描述: The MetaFrame servers reported that they are too busy to launch the selected item.  This was reported from the XML Service at address  .   [Log ID: 10bbd340]

直到看到，

MS DTC has started.

以上日志后，再登陆citrix一切正常！原来是ms dtc未启动的原因！！具体是不是还有其它原因就不知了！
