DFSR Replication Group missing in action

We have DFSR running between win 2003R2 and Win2008std.
The Hub is a win2008 server and we have 9 spokes. The problem started when i noticed that the topology showed that 1 member was disconnected.
The server was read/write configured but the DFS Management only showed the path from the hub to the spoke and not the spoke to het hub.
I added the spoke path with the following command: dfsradmin conn new /rgname:"Profile Replication" /SendMem:server.domain /RecvMem:server.domain /ConnEnabled:true
The connection was made but at the same point the hub server lost connection with the replication group. I removed the replication group from display and tried to re-add it. The replication group is no longer to find.
I removed the member that i added the path from but the replication group did not return. After browsing the net for ages and checking for a way to solve it i decided to ask here for some idea's.
When i check, in dfs management, the namespace replication is states Profiles: The replicated folder object can not be queried. The replication group Profile Replication cannot be found.
When i check on the win2008 spokes the replication group is still available on the win2003 spokes the replication group is not available. I ran a healthreport against the hub server and that runs without errors.
Used the command --> dfsradmin health new /rgname:"Profile Replication" /refmemname:domain\hubSERVER /domain:domain.local /ReportName:hubSERVERreport-%DDMMYYYY%%HHMM% <--

Anyone some ideas or maybe needs/wants some more info?

Thanks in advance,
André
