Acabei descobrindo sobre dfsradmin
e fiz o trabalho funcionar. Este tópico me deu o que eu precisava (o seguinte é fornecido como uma referência no caso do site cair, é claro que eu tive que mudar os nomes):
# Add the namespace server
dfsutil /AddFTRoot /Server:%SERVER% /Share:SharedData
# Add Folder Targets from said server
dfscmd /add \domain\SharedData\%SITE%\users$ \%SERVER%\users$
# Add Folder Targets from Hub Server
dfscmd /add \domain\SharedData\%SITE%\users$ \HubServer\SharedData\%SITE%\users$
# Add Replication Group Info as per DFSRAdmin.doc
