Django + IIS Windows Server 2012 R2 error

I am new into the server "world" and I have to make a django project work from a Windows Server 2012 R2. I followed this tutorial: Installing Django on IIS: A Step-by-Step Tutorial. I have a basic django project. When I start running my server it worked.

Before I removed my custom handler and leave the StaticFile handler as the most important one (according to the tutorial), I tested my site to see if it works:

->If I have added in the FastCGI Settings Monitor changes to file option, then I got HTTP 500.0 Internal Server Error: File monitoring is enable for a file which could not be found - error code: 0x80070003. ->If I removed the Monitor changes to file option then I got HTTP Error 500.0- Internal Server Error C:\Python27\python.exe - The FastCGI process exited unexpectedly error code - 0x00000002.

After I followed the next step from tutorial and I added virtual directory for media and static, and I also removed the previous handler to leave the StaticFile handler as the most important one, I got this result, and when trying to access the admin page, got: HTTP Error 404.4-Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

And when I try to go back to using a custom handler as the most important one, even if I did all the changes back, it keeps using the StaticFile handler, even if I deleted the virtual directories too, and as a consequence I get the same result.

And when I try to run python manage.py fcgi command, it doesn't show anything it cmd, but creates a file in my project directory with the following content: 2016-10-20 12:01:24,013 [DEBUG] _recvall (8) Can anyone help me? I searched on the internet solutions and examples to understand what is happening but none was helpful.
