Let's say you have a 2012R2 iSCSI Target Server with multiple networks configured. We all know that iSCSI traffic should be on a separate network. So how do you go by configuring iSCSI to use a specific network on the target server? In previous version of Windows this was much easier to find since it was in the iSCSI Target software.
1. Start Server Manager
2. Select File and Storage Services in the right pane
3. In the Servers field right click the server name and select iSCSI Target Settings
Now you don't have to worry about iSCSI traffic going over the wrong network in case a clients networks are not configured properly.
