Welcome to the Q&A Forum

I've not come across any reason ever that would give cause to be concerned about losing Page Authority by having a page canonical to itself.

Hi,

This isn't the best forum for this question as it's about IIS configuration - you'd be best off hitting up Windows Server configuration forums.

It is possible to do what you want to do. Dynamic (application) content in IIS needs to run under an application pool in order to be processed. You do this by creating an application under the website in the IIS manager.

Static content typically should sit under a different virtual directory (doesn't need an application). This means you can set it to be cached to improve page load time for users.

My advice would be to go back to the developer and look at his dev server set up, then copy it for your live server. Sorry it's hard to give you any more advice without a lot more information on the environment and code.

Hi,

You'll need to provide the site details if you need help in diagnosing a penalty.

As a starting point I would log into Google Webmaster Tools to see if a manual penalty has been applied, I would also look in Analytics to see if your organic traffic overall has dropped across other pages on your website.

An algorithmic penalty is harder to diagnose, but can usually be recognised by aligning traffic drops with dates of Google algorithm releases.
