Cannot Create Web Application from Central Administration in SharePoint 2013 - Cannot display Web Page

If you are experiencing failure during creation phase of a new Web Application in SharePoint 2013, probably your environment is under capacity planning raccomandations.

What happen is that the process take a very long time but not everything is done in order to have a correctly created web application.

In addition Central Administration UI show you a pop-up "Cannot display web page".

This is due to a time-out in the application pool ping feature.

You can fix this by changing default value for the application pool from 90 to another reasonable value (in my case I've used 360).

Open IIS Manager, go to Application Pools node and then select "Set Application Pool Defaults ...".

Change "Ping Maximum Response Time (seconds)" to a Greater value.

This Application Pool property is available in IIS 7 and greater.

This picture show you this property in IIS Manager.
