DFS 2012 Namespace Architecture Across Domains / Forests

Last Modified: 2015-03-02
Objective: To design DFS hosted on Windows 2012 R2 servers so that performance is optimized in multiple domains.

Situation: DFS access needs to happen from the root domain (J) and 3 child domains (J1, J2, J3), as well as a domain in another forest. Folder target will exist in the parent domain, one child domain, and the domain on the other forest (SKM). DNS is such that shares and servers are visible from all domains. There is a 2-way trust between forests J and SKM.

1. Keep namespace servers in only the root domain (they cannot cross domains). This would probably be slow outside the root domain.
2. Create a namespace in each domain for faster access. (replication only from a single replication group, of course)
3. Other options?

Are there any issues with option #2, or is there a better way?
