MVC4 deployment in IIS7.. 500 internal error

Question

I have MVC4 which is running fine my local IISExpress. Today My admin created brand new Dev server and created new web application under default website. I have published same code into that webapplication folder. when I typed http://dev.company.com/iapps/vol it blows up 500 - Internal server error

How can I troubleshoot this?

Answer 1

The easiest way start debugging the problem is accesing the site from inside the dev server. This way IIS will throw the error to the browser because it's local.

Answer 2

From Windows Explorer, browse to: C:\\Windows\\System32

Find cmd.exe, right click on it and "Run as administrator"

Then in run this: C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319>aspnet_regiis -i
