I am working in a Cyber Cafe and having problem using PalTalk. There are 13 computers in the network and only one computer can use PalTalk at a time. When another person trying logging in i get an error message: Error 10048, Address already in use. Can someone help me solve this problem. I read somewhere that i have to mapping of ports but id ont know how. We use Wingate 4.2 for Internet Sharing. If anyone has solution to this problem please help me.
