The current identity (IIS Apppool\dfcreport) does not have write access to "C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary. ASP. NET Files".

The ASP. NET Web site is deployed above IIS, and browsing appears as shown in the error.

Cause the most

Reason:

1.IIS does not have permission to write to this folder.

2.IIS and ASP. NET install in the wrong order, you should first IIS, and then ASP.

3. Install the ASP. NET environment is not installed.

Solution (corresponds to the above reason number):

1. If prompted, do not write permission, just follow the path to the file found, then right-click Properties, Security tab, add everyone user rights. (The most common solution)

Both the 2.IIS and. NET environments are installed, and you need to re-register ASP. 4.0 for example.
