Cannot add server to DFS replication group

Question

I am trying to add a server to a DFS replication group but I always get error  Servername: information cannot be retrieve for this computer. The network path cannot be found.
THat is the error I get when adding this member to an existing replication group.

Hi,
From the error message it seems like the folder you are trying to add does not exist, or the network is not available. 
Can you directly access the folder you are going to add with \\servername\folder (the same as the path you are going to add)?
If access is fine but still cannot add it as a folder target, test to disable Windows Firewall on both servers. 
Specifically it require following ports to be open.
