1.IIS and . net4.0 installations are sequential, you should install the . NET Framework 4.0 first, and then install IIS. If you install in reverse order,IIS does not see Anything related to 4.0, then you can only perform command enablement:

C:\windows\system32> C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_regii.exe-ir-enable

      2. Iis " "LocalSystem", "Local service", "Network service", using the default " applicatonpoolidentity " So if you are connected to a local database, you may not be able to connect because of security restrictions, and you can change the application identity to "LocalSystem" in the application pool advanced settings process model. Maybe it will be all right.

3.machineKey: It is machine.config by default at the ASP . NET Framework level (C:\Windows\Microsoft.NET\ Framework64\v4.0.30319\config) , It is dynamically generated by the . NET Framework by default , The build on different servers is not the same, but the cluster scenario must be the same, or there will be errors during some encryption and decryption process:

4. Be aware of the differences between the IIS application Pool Classic mode and the integrated mode, which are analyzed according to the specific scenario.

Think down, is not the application pool type reason, a look at the application pool is now using the integration, replaced by classic try,

Change the application pool to classic and then encounter an error:
HTTP Error 404.2-not Found
The page you requested cannot be provided because of the ISAPI and CGI Restrictions list settings on the WEB server.
Then go to IIS7.5 's "ISAPI and CGI restrictions", and see that the ASP. NET v4.0 is in "Disallowed" state,

The 4.0 related to the activation is good ...
