I have a Dell 4100. 512 MB ram, XP home, no sp2. LAN is how we connect. Under network lan properties i have selected file and printer sharing, as well as checking the other boxes. I do not have norton. I have zonealarm, but turned it off. 6346 is the port limewire is using. I have read all threads, and tried all tricks including various versions of limewire, beta included. I am very knowlegeable of networks, and computers. I have come to the conclusion that there is the school firewall interfering somehow. I hope i'm wrong. The bug report says false which means the problem is the firewall. ok theres my info.
