Por padrão, os destinos no site de um cliente são preferidos a qualquer outra referência. Portanto, você pode escolher um método de ordenação para os destinos do site do cliente.
No site da Microsoft: link
The domain controller determines the clients site and returns a list of root targets. By default, the root targets in the clients site are at the top of the list, followed by the remaining root targets in random order. If least-expensive target selection is enabled, the remaining root targets are ordered by lowest cost. If same-site target selection is enabled, only root servers in the clients site are listed in the referral.
Além disso, a partir do DFS, você tem o procedimento para alterar a prioridade das referências:
A referral is an ordered list of targets that a client computer receives from a domain controller or namespace server when the user accesses a namespace root or folder with targets in the namespace. Each target in a referral is ordered according to the ordering method for the namespace root or folder. To refine how targets are ordered, you can set priority on individual targets. For example, you can specify that the target is first among all targets, last among all targets, or first (or last) among all targets of equal cost.
To set target priority on a root target for a domain-based namespace
Click Start, point to Administrative Tools, and then click DFS Management.
In the console tree, under the Namespaces node, click the domain-based namespace for the root targets that you want to set priority on.
In the details pane, on the Namespace Servers tab, right-click the root target with the priority that you want to change, and then click Properties.
On the Advanced tab, click Override referral ordering, and then click the priority that you want.
- First among all targets Specifies that users should always be referred to this target if the target is available.
- Last among all targets Specifies that users should never be referred to this target unless all other targets are unavailable.
- First among targets of equal cost Specifies that users should be referred to this target before other targets of equal cost (which usually means other targets in the same site).
- Last among targets of equal cost Specifies that users should never be referred to this target if there are other targets of equal cost available (which usually means other targets in the same site).
To set target priority on a folder target
Click Start, point to Administrative Tools, and then click DFS Management.
In the console tree, under the Namespaces node, click the folder of the targets that you want to set priority on.
In the details pane, on the Folder Targets tab, right-click the folder target with the priority that you want to change, and then click Properties.
On the Advanced tab, click Override referral ordering, and then click the priority that you want.
