A year later butt...
I was able to install an agent on a lacie appliance from the Lan Discovery, install agent option.
I created a backup post script that schedules a script to run on the lacie appliance to restart the Server (lanmanserver) service, which clears all connections.
net stop lanmanserver
net start lanmanserver
There isn't a computer browser service on the lacie, so it doesn't need to be restarted.
