this is really weird. i have networked my desktop running windows xp pro sp2 and laptop windows xp home sp2 with a hub. everythings working fine, im using the internet of the desktop thru the hub on the laptop but cant share files. I disabled norton internet security 2005 and presto .. the file sharing works... but when i enable it again the file sharing is blocked. i put the laptops IP address and subnet in the trusted computers group in the fire wall config but no avail still the same problem. what am i doing wrong?
