Prevent IIS from recycling if /bin changes

I finally figured it out. There was a 3rd party DLL in the project called safileup.dll that was being used to upload files on the application. Removing that file from the bin directory fixed my hanging issues.

The dll in question was softartisans fileup. We will be discontinuing use of this add on.

This is most likely from the loopbackcheck when testing locally on the server. I bet it works if you test it from another server.

Turn off the loopback check using method 2 from this page: http://support.microsoft.com/kb/896861. A reboot isn't required for your change.

As for permissions, with impersonation enabled it will need the authenticated user, plus the app pool user will be needed some some things. So, the key permissions to use are SYSTEM, Administrators, "IIS APPPOOL\{apppoolname}" and a group for the possible users that will authenticate.
