我在Asp.net程序是用到了访问Excel组件,一本机运行正常。但上传到服务器后出现了如下错误：
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed
due to the following error: 80070005.
Description: An unhandled exception occurred during the execution
of the current web request. Please review the stack trace for more information about the error and where
it originated in the code.
Exception Details: System.UnauthorizedAccessException: Retrieving the COM
class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following
error: 80070005.
ASP.NET is not authorized to access the requested resource. Consider granting access rights
to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET
on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application
is impersonating via <identity impersonate= "true "/> , the identity will be the anonymous user
(typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file,
right-click the file in Explorer, choose "Properties " and select the Security tab. Click "Add " to add the
appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
说明：我已对服务器dcom进行了如下配置，：
（1）打开开始菜单的运行对话框，输入dcomcnfg命令，确定，这时会弹出组件服务窗口
（2）展开计算机-〉我的电脑-〉DCOM配置，找到Microsoft Excel应用程序节点
（3）单击右键-〉属性，选中“安全”选项，在下面三个项目都选择“自定义”，并单击编辑按钮
（4）在启动权限对话框中点击添加按钮，添加相应的用户（注意：如果是WIN2000，XP，则添加“机器名/ASPNET”用户，
我这里是以WIN2003为例，WIN2003是添加“NETWORK Service”用户），并赋予最大权限
请高手们帮助分析一下是什么原因

office com 没有权限

虚拟一个帐户吧
在web.config里

解决办法：
第一步：登录服务器
1，开始－运行：输入dcomcnfg.exe
2,选择excel应用程序点击属性
3，启动/访问授予aspnet用户和network
4，身份标识选择指定用户输入用户名/密码，确认关闭 ----（主要是这句）
第二步：打开服务器模板文件所在文件夹右击选择属性安全
添加用户aspnet,administrator
