Hi. I'm trying to set up a program that will discover and communicate with peer instances on a local network. Ideally listening on a single port number.
Setup: ICSv6 - modified ICSTCPSrv sample program in Turbo Delphi. The code seems to work fine on my XP machine - it picks up its own UDP broadcasts and can pick up UDP broadcasts from a W7 machine and doesn't display any error messages when setting up the TWSocketServer for the TCP listener and TWSocket for the UDP listener (and another TWSocket to do the client send). On starting on either a Windows Server 2008 R2 Standard or Windows 7 machine, it comes up with an error message: Address not available (#10049 in setsockopt(IP_ADD_MEMBERSHIP)). I've set the MultiCast and ReuseAddr properties to true on the listeners. What have I missed to get it working on the other windows versions?
