DFS-R Target not published

Hello everybody,

I have a DFS-N infrastructure with some shared folder replicted on HUB server using DFS-R.
But when i look on mmc shared folders from the HUB server, there is no one connected on the replica.
Then when i go on DFS Managment mmc console on any DFS server i can see that the publication status of my replicated folder  is not published as you can see it in the following screenshot .

Can ou tell me how can i do to make sure users on the same  site that the Hub server can connect it?

Thank you for your help
