I've created a chat program that works great when I loop it back to myself using winsock, it also works great over an internet connection to an IP #. However when I have my computer LANed up with another through our network cards, it doesent detect their IP or host name. Ive tried specifiying one on their network properties and it still doesnt work. Any help would be appreciated. By the way the network isnt the problem because I see the other person fine in my network neighborhook.
