服务器同时存在1.1和2.0程序注意事项

Asp.net和asp.net2.0同时部署在服务器上:发生如下错误

Server Application Unavailable

The web application you are attempting to access on this web server is currently unavailable.  Please hit the "Refresh" button in your web browser to retry your request.

Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.

在事件察看器上看到如下错误：
It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.

如何解决这个问题?
 
2) 为1.1和2.0的程序部署在不同的网站下面。
3) 1.1和2.0的程序的网站分别属于不同的应用程序池

我的上述解释如果你有看不懂的地方，可以同我联系 ;)
