I have a SharePoint 2010 test environment was working perfectly with it's default Web Application and root site. This is a single server install, with its own local copy of SQL.
I've made and deleted a few additional Web Applications for various purposes. These have been deleted with no problems. However, my last one somehow has the same Port Number as the default web application. Nowe my default site doesn't work. I've deleted the web app with the same port number to no success. I've also additionally restarted IIS (with and without /noforce) and restarted the box.
My main app still doesn't want to work. I'm uncertain as to why. Any suggestions / tips on what to do or check would be appreciated.
