The situation is like this. My machine is equipped with .NET Framework 1.1 and 2.0. First of all, the error is caused by the 2.0 program I opened. After I found this error, the program I played 1.1 could not run. I chose the most traditional way to restart my system. The result is still that there is no change, I have to reinstall my IIS, and configure both the 1.1 and 2.0 frameworks. The result is that the 2.0 program can run, and the 1.1 program is still the error. Think about it, think of viewing the application log: change the application pool of the next virtual directory. Let ASP.NET1.1 and ASP.NET2.0 virtual directories use different application pools. The problem is solved, let's get it. ! Upstairs is a master, it is indeed an application pool problem, the ASP.NET2.0 site with a new pool problem will be solved. Steps to create a new application pool 1.

This problem has been seen several times. In the .NET under Microsoft Visual 2005->visual studio tools->visual studio 2005 command prompt, enter aspnet_regiis -r, you can just re-register it because this is because You installed .net and then installed the permissions of the iis user.
