The connection troubleshooter window automatically opens when Yahoo! Messenger detects a connection sign-in issue. So you have to check that all your cables are connected, restart your modem, or restart your router. For Windows issues, go to the Windows online help and search for terms like "DNS" or "Firewall" to locate information about the proper settings. If you follow the Windows online help instructions, they should provide you with the steps for entering the proper settings.
