剛才碰到“Microsoft OLE DB Service Components 類別未登錄” 錯誤,去網上搜了一下結果，找到了"未找到oracle 客户端和网络组件"問題詳解這篇文章，按此方法，解決了我的問題。現摘錄如下：
今天在测试ASP.NET程序，在连接ORACLE数据库时报出了“Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed”的错误。可我本机上确确实实已经装了Oracle Client,而且在我本机上运行时也正常，一旦通过IIS发布，在运行时就会报上述错误。通过查找网络资料，该问题已经成功解决。现将解决过程发布，供大家参考。
首先，把可能出现该问题的情况简单阐述一下：a:Oracle 9.02i 版的问题b:是NTFS格式分区造成的。Oracle公司对此问题也给出了描述：
Problem Description ------------------- When running an application that connects to Oracle and uses the Authenticated User privilege (such as Microsoft’s Internet Information Server (IIS)) via Oracle’s 9.2 client software and any of these programmatic interfaces
1. Oracle Provider for OLE DB
2. Microsoft OLE DB Provider for Oracle
3. Oracle ODBC Driver
4. Microsoft ODBC for Oracle
5. Oracle Objects for OLE (OO4O) you will receive one of the following errors:
(1) Oracle Provider for OLE DB Error Type: Microsoft OLE DB Service Components (0x80070005) Access is denied.
(2) Microsoft OLE DB Provider for Oracle Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. Or Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle error occurred, but error message could not be retrieved from Oracle.
(3) Oracle ODBC Driver Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80004005) Specified driver could not be loaded due to system error 5 (Oracle in OraHome92).
(4) Microsoft ODBC for Oracle The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3 (or greater) client software installation. You will be unable to use this driver until these components have been installed.
(5) Oracle Objects for OLE
(a) while using a GLOBAL.ASA file Error Type: Active Server Pages (0x0) An error occurred while creating object ’OraSession’.
(b) not using a GLOBAL.ASA file Error Type: Microsoft VBScript runtime (0x800A0046)Permission denied: ’CreateObject’
(6) Other miscellaneous errors (a) The Specified Module Could Not Be Found
接着，我们来解决此问题，方法很简单，找到ORACLE_HOME文件夹，右击—〉属性—〉安全，选Authenticated Users，查看它的属性，将Read and Execute的勾先去掉（默认情况下该勾是选中的），在勾上，然后重新启动你的机器，在运行程序，该问题就成功解决了。
ORACLE公司也给出了解决方案：Solution Description -------------------- You need to give the Authenticated User privilege to the Oracle Home by following these steps:
1. Log on to Windows as a user with Administrator privileges.
2. Launch Windows Explorer from the Start Menu and and navigate to the ORACLE_HOME directory.
3. Right-click on the ORACLE_HOME folder and choose the "Properties" option from the drop down list. A "Properties" window should appear.
4. Click on the "Security" tab on the "Properties" window.
5. Click on "Authenticated Users" item in the "Name" list (on Windows XP the "Name" list is called "Group or user names").
6. Uncheck the "Read and Execute" box in the "Permissions" list (on Windows XP the "Permissions" list is called "Permissions for Authenticated Users"). This box will be under the "Allow" column.
7. Check the "Read and Execute" box. This is the box you just unchecked.
8. Click the "Apply" button.
9. Click the "OK" button. 10. You may need to reboot your computer after these changes have been made. Re-execute the application and it should now work. Explanation ----------- If you install Oracle9i Release 2 (9.2.0.1) on a computer running Windows with an NTFS partition, the contents of ORACLE_HOME directory will not be visible to users who are authenticated on that machine. These permissions were not set properly when the software was installed. Applications that were working fine with previous versions of Oracle software will stop working when they upgrade to Oracle 9.2.
NOTE: The application will continue to work if the user has logged onto the machine as an Administrator. Any application that is using the Authenticated User privilege will not work. A notable example would be IIS which might service some of the requests based on the Authenticated User privileges. To demonstrate the problem in further detail, you can log on to the operating system as an authenticated machine user. You won’t be able browse the contents of the ORACLE_HOME directory demonstrating your inability to load any Oracle DLLs or make a connection.

需要注意的是：在XP系统下，属性中可能找不到安全选项卡，如何去解决呢？很简单，打开一个窗体，选择“工具”—〉文件夹选项...—〉查看，将使用简单文件共享前的勾去掉，确认即可。
