Application Servers use the Darwin Streaming Server to stream video thumbnails from some network devices to iControl applets running on client PCs. For example, when you open a video card’s control panel from iC Navigator, the control panel displays a thumbnail representation of the current video signal.

In order for such streaming to work properly, a client PC’s internal Domain Name Service (DNS) must be able to resolve the host name (and reverse resolve the IP address) of the Application Server from which the applet was launched.

In order to avoid slower streaming performance, you should make sure that each client PC has all available Application Servers and Allégro‑1 systems listed in its DNS configuration file.
