How to resolve 'File Not Found' error while trying to open Site Settings for Business Portal

I was trying to setup the company logo for the Business Portal this morning. When I tried opening 'Site Settings' I was getting 'File Not Found' error. After doing a google research (as always), I realised that this is something to do with 'Alternate Access Mappings' in SharePoint Central Administration for SharePoint Foundation 2010.

By default, SharePoint Foundation 2010 creates Alternate Access Mappings based on the workstation name. I was trying to open the Site Settings using the URL http://localhost. There was no Alternate Access Mappings configured for http://localhost. After setting it up, hurrayyyy, it started working.

Please see below the steps to setup the Alternate Access Mappings for SharePoint Foundation 2010.

• Open Start >> All Programs >> Microsoft SharePoint 2010 Products >> SharePoint 2010 Central Administration
• Click on Application Management
• Click on 'Configure alternate access mappings' under 'Web Applications'
• Make sure you have selected the right Web Application for 'Alternate Access Mapping Collection'
• Click on 'Add Internal URLs'
• Enter the URL. In my case, I typed http://localhost
• Click on OK

That is it. Now it should work!!
