This method uses the so-called Local Discovery Server (LDS). You can influence how the discovery works using the properties in SharedParameters. The name of the machine that runs the discovery is determined by OpcLabs.EasyOpc.UA.Engine.EasyUAInstanceParameters.DiscoveryHost in InstanceParameters, and defaults to "localhost".

Invokes the FindServersOnNetwork service.
