系统日志有以下的错误信息：
错误: 应用程序池 'DefaultAppPool' 的模板永久性缓存初始化失败，这是由下列错误所导致: 无法创建应用程序池的磁盘缓存子目录。数据可能包含额外的错误代码。
Windows Server 2003 无法创建应用程序池的磁盘缓存子目录的解决办法
处理方式:给下列三个目录授予IIS_WPG及Service用户的读写权限：
• systemroot\Help\IISHelp\Common
• systemroot\System32\Inetsrv\ASP Compiled Templates
• systemroot\IIS Temporary Compressed Files
• %systemroot%HelpIISHelpCommon IIS_WPG和NETWORK SERVICE 读取和运行权限
• %systemroot%System32InetsrvASP Compiled Templates 两者完全控制权限
• %systemroot%IIS Temporary Compressed Files 两者完全控制权限

自从公司服务器升级为域控制模式以后，发现IIS上运行一些ASP的应用程序时，会时不时出现类似下面这样的错误信息：
错误: 应用程序池 'DefaultAppPool' 的模板永久性缓存初始化失败，这是由下列错误所导致: 无法创建应用程序池的磁盘缓存子目录。数据可能包含额外的错误代码。
经查询相关资料后发现这个错误是IIS运行权限的问题，处理方法是更改IIS运行时用的两个帐户：IIS_WPG 和 NETWORK SERVICE 对应用程序池用到的相关目录的NTFS权限，将IIS_WPG帐户设置为读取与执行、列出文件夹目录、读取，而NETWORK SERVICE则需要完全控制权限。 (此话不完全正确)
要配置的相关目录有以下几个：
• %systemroot%HelpIISHelpCommon
• %systemroot%System32InetsrvASP Compiled Templates
• %systemroot%IIS Temporary Compressed Files
附：%systemroot%通常指C:Windows，如果你是从Win 2K Server升级到2003，则是C:Winnt。如果你自定义了系统目录，是根据实际情况调整这个变量的值。
完成后，重启一下IIS Admin服务，即可解决此问题。

When you use Filemon to monitor file activity, you receive an error message that is similar to the following:
3521 Time w3wp.exe:3168 CREATE C:WINDOWSsystem32inetsrvASP Compiled TemplatesPID3168.TMP ACCESS DENIED NT AUTHORITYNETWORK SERVICE
CAUSE
This issue may occur if the server that is running Microsoft Internet Information Services (IIS) 6.0 is also a domain controller. The problem occurs because the Application pool is using the NT AuthorityNetwork Service account, and the NT AuthorityNetwork Service account may not have permissions to access the required folders.
RESOLUTION
To resolve this problem, manually set permissions on the folders for the IIS_WPG group, and then set permissions on the folders for the NT AuthorityNetwork Service account.
To set permissions on the folders for the IIS_WPG group, follow these steps: 1. Start Windows Explorer, and then open the following folder:
%systemroot%HelpiisHelp
2. In the right pane, right-click the Common folder, and then click Sharing and Security.
3. Click the Security tab, click Add, type IIS_WPG, and then click OK.
4. With IIS_WPG selected, click to select the following check boxes under the Allow column, and then click OK: Read and Execute

7. Click the Security tab, click the IIS_WPG group, and then click to select the Full Control check box under the Allow column. Click OK.
8. Open the following folder:
%systemroot%
9. In the right pane, right-click the IIS Temporary Compressed folder, and then click Sharing and Security.
10. Click the Security tab, click the IIS_WPG group, and then click to select the Full Control check box under the Allow column. Click OK.
To set permissions on the folders for the NT AuthorityNetwork Service account, follow these steps: 1. Start Windows Explorer, and then open the following folder:

12. With the NETWORK SERVICE group selected, click to select the Full Control check box under the Allow column, and then click OK.
After you have completed these steps, restart the IIS Admin service from the Services snap-in or from the Computer Management snap-in.
