By assigning target priority for individual root targets or folder targets, you can specify whether a target server appears first or last in a referral. Assigning target priority is useful in many scenarios, such as "hot standby" scenarios where one server is considered the server of last resort. In this scenario, you can specify that the standby server always appears last in referrals, and clients will fail over to this server only if all the other servers fail or become unavailable due to network outages. If multiple servers are configured for always first (or last), then those servers will be sorted based on the overall prioritization (random or lowest cost).
To change target priority, see Set target priority to override referral ordering.
