Windows Home sErver “Beeping misery”

My client has a recently installed machine running Windows Home Server.
This is the only home server I have any knowledge of, in fact I built it myself.
If the server detects any kind of connectivity issues on the network it “beeps” via the motherboard system speaker, it seems to depend on the severity of the problem how often or how regularly it beeps.
The client has reported that the machine is beeping again today but is not reporting any issues on the network.
Does anyone know how to disable the beep warning in home server?
