The TROZeroConfBrowseEngine class is used internally by the ZeroConf infrastructure to retrieve information about the ZeroConf environment and services registered in it. You should not use this class directly. To discover services, use the TROZeroConfBrowser methods.

Note: Take a look at the BonjourDiscovery sample shipped with the Remoting SDK to see service discovery in action.
