EPiServer CMS 5.2.375.133 Intranet site

We use WindowsRoleProvider and all users become at Active Directory.

Page contains picture or link to file. When user entering the site everything work properly. But when user update browser, for example, press F5, user lost his read permission each file on page ?

There is no any permissions for Everyone group, all users are members of Users -group and Users -group has read permission to all pages. If we add Everyone -group and read permission for this group, everything work properly?

Is this some kind of impersonate problem ?
