Hey guys, I'm working on a Messenger system and I'm using UDP on the client side to detect which host the server is running from. It works fine but on Windows 7 systems administrator privileges are needed to listen on ports. The machines the clients are to run on require the Administrator password to do so. It does not however need the administrator password on the TCP side since the server is doing the listening. Is there another method or solution for this? Would not mind another method of detecting the server either. By the way it's a LAN based messenger.
