When a child site has received a link request from a potential parent site where the administrator did not have administrator rights to the child site, it has the awaiting acceptance icon.
To accept a link request:
If the site runs the XProtect Expert version, you right-click the site in the Site Navigation pane.
Changes that you make to child sites located far from the parent site can take some time to be reflected in the Federated Site Hierarchy pane.
