When creating a new Web Application in SharePoint 2013 you might get this message in the “pop up” window: Internet Explorer cannot display the webpage like in the following ScreenShot:
This is usually because you either have too many Web Applications in your SharePoint Server, or because your SharePoint Server is slow! As part of the Web Application creation process, SharePoint resets IIS. By Default, the application pool only allows for 90 seconds for all the connections to close before it down by force. If you got this message it’s because 90 seconds wasn’t enough and we need to increase that limit.
The solution to this is to allow the process a longer amount of time before it is forcibly shutdown.
- On the server(s) hosting Central Admin, open IIS manager.
- In the tree view, expand the server name and click on Application Pools.
Locate the SharePoint Central Administration v4 application pool. Right click on it and choose Advanced Settings.
In the Process Model section, set the Shutdown Time Limit to a greater value. As an example, 300.
- Restart IIS.
You should now be able to create Web Applications without any troubles!
