在访问IIS7的网站时，可能会遇到Service Unavailable的错误，错误的原因当然可能会有很多种，因此需要使用Just-In-Time Debugger来go into到实际的内部错误。

**错误信息**：  
System.ServiceModel.CommunicationException was unhandled  
  Message=There was an error in serializing body of message SearchRequest1: '**Unable to generate a temporary class** (result=1).  
error CS2001: Source file '**C:\\Windows\\TEMP\\**s0phakvt.0.cs' could not be found

**解决办法：**  
右键点击**C:\\Windows\\TEMP** 目录，选择 properties->security ，添加 MachineName\\IIS\_IUSRS 账户（将MachineName替换成实际的服务器名称），给予它Read、Write、List等权限。再重新访问这个ASP页面，问题应该能够得到解决。

**原因分析：**  
应该是在你的ASP页面中，调用了别的Web Service/WCF Service，ASP.NET Web Service有时候会在处理WebMethods时使用到C:\\Windows\\TEMP文件夹，因此需要给IIS的相关账户赋予相应的权限。
