程序传到主机上面上去后，连接数据库的时候报下面的错误信息
Server Error in '/' Application.
--------------------------------------------------------------------------------
Retrieving the COM class factory for component with CLSID {2206CDB2-19C1-11D1-89E0-00C04FD7A829} 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 {2206CDB2-19C1-11D1-89E0-00C04FD7A829} 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.
Source Error:

从提示信息来看应该是权限问题引起的，所以试着将应用程序池的标示用户改为系统用户（即SYSTEM权限），然后访问网站，没有任何问题。但是改回来后问题依然存在。查阅N多资料，没有找到理想的答案。于是我在注册表中找到2206CDB2-19C1-11D1-89E0-00C04FD7A829，发现是OLE DB，果然不出所料，是ACCESS数据库连接出问题了。应该是没有权限。OK，找到目录C:\Program Files\system\ole db，给IIS_WGP用户适当的权限，OK，TRY AGAIN。TMD，问题依旧。又查找资料，无果。后来一下子想到我的主机是64位的，应该改这个目录的权限C:\Program Files(x86)\system\ole db.因为我把IIS的有个什么什么enable64bit 什么的东东给激活了，说白了就是64位的主机上面运行32位的程序的意思，所以目录也要相应的改一下。OK，重设定权限，浏览器访问一下，没有报错，页面正常返回。高兴中。。。(本文出自于西宁威势电子信息服务有限公司，欢迎转载，但请注明出处)
