在xp系统下安装iis后,测试内部服务器有错。又出现下面错误：
Server Application Error
The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance.

怎么解决？我在win2000系统上安装也出现同样的错误，什么原因呢？急需解答！
