I USE MICROSOFT WINDOWS XP.
I DID THE PROXY SETTINGS.
In LAN Settings HAS THE ADRESS OF UNIVERSITY PROXY SERVER.(I DONT KNOW THE PORT OF THIS PROXY)
Please, avoid CAPS, you're not yelling
proxy server name: localhost
proxy server port: 12080
or not?
No. This works, as explained in the help files and FAQ, to Windows 98 and Me. Not for XP, which does scan the web traffic transparently, without the need to use a local proxy (localhost:12080).
You need to ask to your university network administrator, the IP address and the port number of the proxy server.
