I too am having the same problems with wins sp2 and LW, I am definitely behind Windows firewall and can not figure out how to work around it or better yet through it. I've tried most of the fixes on this site but none have work so far. I have a Dell Dim4 pc and I am running wins xp home edition I have uninstall Mcafee Virus SW, are there any more suggestions out there if so let us hear from you. I have found the following link on microsoft web site Troubleshooting Windows Firewall settings in Windows XP Service Pack 2 for advanced users
