系统运行环境：windows server 2003 sp2
所加载的是一个第三方的报表控件，编号为{1A90D3D3-6F3A-45E9-93EF-6F7ED2F16898}在COM +应用程序中，我参照网上的解决办法进行设置，但没成功.

最后找到解决方案:

运行dcomcnfg打开组件服务,

依次展开"组件服务"->"计算机"->"我的电脑"->"COM+应用程序"

找到对应的应用程序

右键打开属性对话框,点击"标识"选项卡,

点"下列用户",把管理员（Administrator）的用户和密码（登陆服务器的密码）正确填写进去。但一旦重新装系统或者密码变化后需要重新在此处设置密码。
