in my sharepoint server 2013 backend i can not go to web application root host name but if i add the default.aspx end of hostname i can see the page.
i mean that;
i can not go to web site if i write that url: 'http://sharepointsite.intra' and it shows 404 error.
i can go to web site if i write that url: 'http://sharepointsite.intra/deafult.aspx'.
in addition to these;
i can go to web application site directly another backend.
