Search the network of a large number of data, the problem is more classic, there are many errors, but the domestic and foreign sites and forums but there is no more perfect solution. After some groping and try, finally have a better solution. There are three, as follows:
1. Reopen an application pool and specify this pool separately for this directory
2. Access permission setting problem
3. Reinstall IIS and reload the framework

The situation is like this, I have the machine fitted. NETFramework1.1 and 2.0, first of all, I opened the 2.0 program to appear this error, after discovering this error, I hit 1.1 of the program can not run.

As a result, the problem is not changed, so I have to reload my IIS, 1.1 and 2.0 two frames are configured, the result is 2.0 of the program can run, 1.1 of the program or that error.
