Need help with DFS using 3 DC's, which DC manages root domain namespace?

Ok so i'm fairly new to this organization and i'm trying to implement DFS. Here is the current setup:

DC01 -> Main DC / DFS Namespace+Replication (Installed by default for SYSVOL/NETLOGON)

DC02 -> Secondary DC / NO DFS

DC03 - > DFS Namespace (Installed by me to create DEPTS\HOME\PUBLIC etc,.)

When I go to domain.local all I see is NETLOGON and SYSVOL, so how do I get the namespaces on DC03 to show up? I only see them when I navigate to to \\DC03, so is it using DC01 by default?

Thanks
