Question

我正在我的一个asp.net应用程序中实现Export To Excel功能。我有两个服务器（QA和开发）。在开发服务器中，它工作正常，但在QA服务器中我遇到错误。

    An exception of type System.Runtime.InteropServices.COMException occurred and was 
caught. Source:mscorlib;Message:Retrieving the COM class factory for component with CLSID 
{00024500-0000-0000-C000-000000000046} failed due to the following error: 8000401a The 
server process could not be started because the configured identity is incorrect.  Check the username and password. (Exception from HRESULT:

我在两台服务器上配置了同样的东西，但QA服务器仍无法正常工作。我接下来该怎么办？任何想法...... ??

Answer 1

您的QA服务器上是否安装了Excel 2000？至少它无法启动自动化......

Excel.Application版本独立的PROGID和   {00024500-0000-0000-C000-000000000046} CLSID。 COM相关注册表   Excel 2000的条目包括以下内容：   HKEY_CLASSES_ROOT \ Excel.Application \ CLSID默认值：   {00024500-0000-0000-C000-000000000046}   HKEY_CLASSES_ROOT \ CLSID {00024500-0000-0000-C000-000000000046} \ LocalServer32

默认值：C：\ PROGRA~1 \ MICROS~1 \ Office \ EXCEL.EXE / automation By   从PROGID到CLSID的注册表项之后，COM即可   了解Excel可执行文件的安装位置并启动它   自动化。

我遇到了一个类似的问题，在会话之间身份丢失了，我不得不再次提供凭据来暂时修复它。在调查它时，我发现了一篇文章，建议授予用作“登录为批处理作业”权限的域帐户权限，因为如果未授予权限，则AD在执行更新时将丢失该身份。
