500 - Internal Server Error ASP.NET (IIS 7.5)

Question

I am now in the process of transferring my servers to windows azure. I created a virtual machine ( 2008 R2 ) and installed IIS 7.5 . I then transferred one of the site ( DNN ) and configured it to with it's own apppool (4.0) and granted permission for this app pool to read and write.

I have two domains: one internal, which I defined in the HOST file, and one public (mydomain.com). The internal domain works fine however with the external domain I'm getting:

500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.

Answer 1

Perhaps, you haven't set up endpoints for the server on the portal to allow HTTP traffic? In other words, did you open up port 80 on the Azure portal for this VM?
