This post I’m as a reminder because a few days back when I was working on a production environment for one of our clients. I had created an extended web application and needed to remove it. In SharePoint 2007 I have done this several times but in 2010 I had to take a good look.
To delete the extended web application you need to do the following:
- Start Central Administration.
- Go to Manage Web Applications.
- Select the web application you extended.
- Click on the Arrow beneath Delete and select Remove SharePoint from IIS Web Site.
- Select the Web site.
- Finally click OK
