text: internet connection is working fine, but local lan has gone crazy. what are the steps to take to make it right just reconnected to a new isp, and i must have tinkered too much with my lan card's settings. now i am in trouble. helpppppppp. you must log into your computer using a password to get local area network access to work properly, using client for microsoft networks willl also require all of the computers on the same local area network to have the same work group name.  check your internet tcp/ip properties and besure that your lan subnetmask are all the same on all the computers :) good luck
