Hi, i looked for the 'exceptions' tab because i used it on my pc (i do have sp2) but it wasn't there. So i 'ticked' the "pop3,SMTP,HTTP" etc boxes and i had it working when i left his house. I sent him an e-mail when i got home and he couldn't receive it or go on the internet. Before sp2, i had no probs with the basic firewall and I.E/ Outlook. very strange.Any more thoughts?
