Got no idea from Exchange side, do you think question2 leading to question1?
See if you can access OWA/ECP after you solving the IIS issue.

I can get to OWA but not ECP, in IIS this is the error I get when I click on any of the sites and any icons in the sites. see Image

Hi,
I work for Exchange, and I know little about IIS troubleshooting.
Did you meet the error after you enter user's password, or when you open the ECP page?
Please try other URLs like https://ex1.domain.com/ecp/?ExchClientVer=15, or https://localhost/ecp .
Normally we could recreate ECP url with EMS commands:

Remove-ECPVirtualDirectory "ecp (default web site)" New-ECPVirtualDirectory -name "ECP" -WebSiteName "Default Web Site" –InternalURL https://internalURL/ecp

But for your issue, I suppose it might be resolved after you fix Question2 and run IISreset.
