You create a Microsoft ASP.NET Web application by using the Microsoft .NET Framework version 3.5. 
You deploy the application on a Microsoft IIS 6.0 Web server. The server runs on a worker process isolation mode， and it hosts the .NET Framework version 1.1 Web applications. 
When you attempt to browse the application， the following error message is received： 
"It is not possible to run 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." You need to ensure that the following requirements are met： 
&iexcl；¤All the applications run on the server
&iexcl；¤All the applications remain in process isolation mode 
&iexcl；¤All the applications do not change their configuration.
