Say I have the domain 'contoso.com', which is resolved by a domain controller (Controller). I have a share (Share) on Controller with everyone permissions (full control, just to test).
Now I can access Share via '\\Controller\Share' or '\\Controller.contoso.com\Share'. This is fine.
I can also access Share via '\\contoso.com\Share'. This is not fine, as follows.
If I try to e.g. create a new folder, I get 'Could not find this item. This is no longer located in contoso.com.'
Why is Share listed in the shares of contoso.com if it isn't located there?
