Brand new MVC Asp.Net Project Loads default page, but 403 after for anything else

Question

I created an ASP.Net MVC project and when I deploy and publish this project the default page will load and appear to work fine, however, if I try to leave to any other URL I get a 403 error. I checked IIS event logs and found this anytime I click a link.

I have not changed any of the defaults and I left everything as the template created. I used Web deploy and everything appears to work. I have heard it has something to do with my routing, or possibly something to do with headers. But I can completely lost.

Page Load

Any help would be greatly appreciated as I am stuck. I have followed most normal steps like assuring permissions, checking framework versions, etc. I feel it is either something in my code, or something I missing on the server, whatever it is, I am sure its a small setting that i need to change, I just don't know what it is. The project is an ASp.Net 4.5.2 project by the way.

After creating new project with no authentication. This still shows up in Event Viewer as the problem:

So I finally figured out the issue. With all the solutions online nothing worked, and I finally figured out that it was due to the fact I wanted to hose this site in the same location as a Wordpress site. I did not know this, but Wordpress for SEO friendly URL's has a URL Rewrite function. I added my new folder to an exclusion rule and bam, it all worked. Thanks for the help!
