OK, I am trying to set up a very simple test. I have 2 laptops connected to each other (and ONLY to each other) via a lan switch. I have no internet, no wi-fi or anything else connected other than 2 ethernet cables and a 4 port ethernet switch. Both laptops are running Win 10. I loaded the mIRC v7.65 on both laptops. I do not have a separate IRC server running because I was trying to use the server option in mIRC. I am trying to talk between the two laptops and I keep getting the "Waiting for ack...", "Unable to connect", and "DCC session closed" notifications. The firewall on both laptops is completely turned off. I have tried the "server option" on both laptops. Any suggestions? This is the first time I have tried using IRC.
