檢索 COM 類工廠中 CLSID 為 {00024500-0000-0000-C000-000000000046} 的組件時失敗，原因是出現以下錯誤: 8000401a
先用骨哥 狗了一會,沒解決方案,又用擺渡,也沒找到方法,最后還是看微軟的幫助解決了問題:

1.打開DCOM配置，取消交互式用戶，使用啟動用戶

2.安全中附足夠權限，不知道用戶是誰就寫Everyone

SYMPTOMS
< type="text/javascript">loadTOCNode(1, 'symptoms');
When no user is interactively logged on to the server console, if you try to start a COM+ application remotely (either through a Terminal Server session or from a remote client application), the application may fail with the following error message:
8000401A - "The server process could not be started because the configured identity is incorrect. Check the username and password."

CAUSE
< type="text/javascript">loadTOCNode(1, 'cause');
This problem occurs because the default identity for the application is set as Interactive User. Interactive user refers to the user that is logged on directly to the server console. If no interactive user exists, the application fails when it tries to assume the interactive user's identity.

RESOLUTION
< type="text/javascript">loadTOCNode(1, 'resolution');
To resolve this problem, change the identity for the server application to run under a particular user. To do this, on the Identity tab of the Application Properties dialog box, click This User. In addition, if it is feasible, you can ensure that a user is interactively logged on to the server console while the application is running.

WORKAROUND
< type="text/javascript">loadTOCNode(1, 'workaround');
In Microsoft Windows Server 2003, work around this problem by using the /Console switch to log on to Console0. To do this, follow these steps: 1. Click Start, click Run, type mstsc /console, and then click OK.?
2. Log on to the computer.

MORE INFORMATION
< type="text/javascript">loadTOCNode(1, 'moreinformation');
Steps to reproduce the behavior
< type="text/javascript">loadTOCNode(2, 'moreinformation'); 1. Create a new, empty COM+ Server application. Accept the default settings.
2. Add any component to the application. The component must not already be in another COM+ application.
3. Try to start the application remotely when no user is interactively logged on to the server console.
