I need to have a server on one machine that broadcasts a message sever second or so, Kind of like a service discovery.

The message needs to be received by multiple client processes that could be on the same machine or different machines.

Im using delphi7, with indy 9.0.18

where im stuck is if i should be using UDP or IP MultiCast or if its even possible...

Ive managed to get it to work with IP Multi Cast with one client per machine, but even after many trys with different bindings.. max/min ports etc, i cant seem to find a solution.
