IIS访问ASP页面时报错The requested resource is in use.的解决办法

答案：
重启服务器IIS服务后发现所有ASP页面显示http500错误,大汗, IIS中,当将应用程序进程保护设为低时,网站asp程序可以正常运行,但当将应用程序进程保护设为中和高时,asp程序均显示http500错误. 
在网上寻找解决方案,说是IWAM用户密码不同步的原因造成,但查看日志文件,发现日志里记录的描述与IWAM用户密码不同步的不一样, 具体日志如下:

运行时环境在其内部状态检测到不一致。请向 Microsoft 产品支持服务部门报告此错误。*** Error in __FILE__(926): Application image dump failed. C:\WINNT\system32\com\dmp\{3D14228D-FBE1-11D0-995D-00C04FD919C1}_2005_10_13_11_05_35.dmp  

经查看具体的HTTP500错误,显示为: 
The requested resource is in use 

1，权限问题，找到system32下的VBSCRIPT.dll和JSCRIPT.dll给与everyone 读取，运行权限。 

2，依此在国外的网站寻找结果. 
发现是VBSCRIPT和JSCRIPT的DLL注册丢失所致, 
依下面的方法重新注册DLL组件后问题解决,特此记录. 

First:  

If you go into IIS for our site and go into the Home Directory area, click on the Configuration button. You will see a "Cache ISAPI Applications" option. You should ONLY turn this off for testing purposes. When you turn it off, if two people try to hit the same page at the same time they will get: 

The requested resource is in use  

When this is off, you will also see an event log entry for EVERY time an ISAPI is loaded and unloaded from memory - i.e. constantly. 

Check this box in order to cause the items to cache in memory - therefore always being available. 

Also:  

We ran into this problem and it was due to a corruption of the  
vbscript.dll as we noticed it was not running. 

The steps we took to fix it were: 

1) c:/winnt/system32 
2) regsvr32 vbscript.dll 
3) regsvr32 jscript.dll 

This seemed to fix it although we had to mess around with the IWAM as we  
adjusted that when trying to fix the error 

Hope this helps 

Incidentally this happened due to the roleup patch just released so  
beware...
