Hello, I am pulling out my hair on this one. Hope someone can help me. I have a (normally) really easy setup with 3 PC's. PC 1= Internet Gateway with winxp ICS/ICF over dialup PC 2= Desktop as client PC 3= Laptop as client Static IP's 192.168.0.1... My problem is that I have a connection to the internet with internet explorer, but absolutly no other protocols work over the ICS. i.e. Outlook can find pop/smtp server, but can't exchange info & get email VPN to work can be connected, but no network resources are available. Pertaining to the outlook I have tried to manually open ports 110 & 25, which worked until I restarted the PC1. Then it never worked again. I really need this connectionfor work, anyone have an idea? thanks, dbag
