Today I’ll talk about a problem that may arise during the implementation of a SharePoint site.
Problematic : When you access your site via a non-full link (sample : http://server/ ) you are not redirected correctly to the default page (sample : http://server/pages/default.aspx ) and receive an access denied.
If you put a security system on your application (ISA server or other) and you receive an Access Denied (where you should have the permissions), check in IIS that the “Forms Authentication” is enabled for your web application.
This is the authentication that is responsible for making redirects. Once these on, you should be able to access your site.
Hope this helps !
