AIK Version 2 (aka for Windows 7): would wait for IP address before launch application.
PROBLEM: When I start a Multicast, I loose network connection or limited traffic.
SOLUTION: To throttle your multicast bandwidth usage:
From the WDS MMC, open the Server Properties page. Go to the Network Settings Tab. Select the Custom network profile.
In the registry, browse to HKLM\SYSTEM\CurrentControlSet\Services\WDSServer\Providers\WDSMC\Profiles\Custom and set the TpMaxBandwidth setting to something less than 100. It's the percentage of available bandwidth that the server uses.
