DFS and UNC Paths

Does DFS path UNC traffic to a 'primary' DFS server?
I am trying to get a server to path to a particular file server but it keeps redirecting to a different file server.  I believe this could be a networking/Firewall issue but would like to eliminate anything to do with DFS.

Thank you.

you can just disable the folder target, right click the target and go to disable then it will force you to go to the remaining target.

DFS uses your AD Sites and Services definition to select the closest server to you. In AD sites and services you should have several sites with associated IP subnets: DFS will determine what's the site your PC is in, and direct you to a server in the same site. If there is none, it will use whatever is closest by looking into DNS records to see which one is on a "less costly" link.
