Does anyone know if you can add in DFS a new target folder, create a "COST" to it so that it should not be accessed unless the source array becomes unavailable?
So, in short.
A DFS share would look like this.
DFS Share = \\produciton\myshare
the second folder would have a cost associated so that resoltuions would not cross the WAN.
In theory costing and subnets in AD would work, in practice it breaks down easily. We have tested this but found it failed in several scenario's resulting in read-only data for the user.
