最近公司要求编写一个ASP.NET页面下的导出Excel功能, 代码写完之后,在调试的时候可以完好运行,然而正式发布到WIN2003服务器上的时候,却出现了问题.
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.
中文翻译为:检索 COM 类工厂中 CLSID 为 {00024500-0000-0000-C000-000000000046} 的组件时失败，原因是出现以下错误: 80070005
在网络上查找了许多资料,原来是对于用户来说,对服务器上的文件的操作权限不够所引起的错误,要配置DCOM.
具体配置方法如下:
1:在服务器上安装office的Excel软件.
2:在"开始"->"运行"中输入dcomcnfg.exe启动"组件服务"
如果是2000 server 则 在弹出的窗口中选中 Microsoft Excel 应用程序 ,点击属性,然后依次点中自定义配置->添加->显示用户->aspnet ,注意最后一项选中完全控制即完成设置.
3:依次双击"组件服务"->"计算机"->"我的电脑"->"DCOM配置"
4:在"DCOM配置"中找到"Microsoft Excel 应用程序",在它上面点击右键,然后点击"属性",弹出"Microsoft Excel 应用程序属性"对话框
5:点击"标识"标签,选择"交互式用户"
6:点击"安全"标签,在"启动和激活权限"上点击"自定义",然后点击对应的"编辑"按钮,在弹出的"安全性"对话框中填加一个"NETWORK SERVICE"用户(注意要选择本计算机名),并给它赋予"本地启动"和"本地激活"权限.
7:依然是"安全"标签,在"访问权限"上点击"自定义",然后点击"编辑",在弹出的"安全性"对话框中也填加一个"NETWORK SERVICE"用户,然后赋予"本地访问"权限.
这样,我们便配置好了相应的Excel的DCOM权限.
