Anonymous users are having issues with SharePoint 2010 search results where a subsite's welcome page is being returned in the results with a URL of - 'http://sitename.com/subsite/pages' instead of 'http://sitename.com/subsite/pages/default.aspx' OR 'http://sitename.com/subsite/'
When the user clicks on the 'http://sitename.com/subsite/pages' link they are being redirected to the login page.
The user has no issue browsing to these pages using the navigation on the site, or just appending '/default.aspx' or by removing '/pages' from the URL - 'http://sitename.com/subsite/pages' returned in the results.
The viewformpageslockdown feature has been enabled on the site and anoymous access has been granted to the whole site.
Any ideas how to fix this would be appreciated.
