Hello nice people,
I have installed Fedora 11 on my PC at work in a active directory domain environment, and I couldn't join the domain to access internet.
But I (legally) managed to access through a (secret) proxy
I defined this proxy in my browser and worked fine, and also I defined this proxy in the "network proxy preferences"

Finally I could access internet but i am not able to update or download packages through YUM.

I always got the message: "The package download failed"

is there any configuration that should be done?

thanks a lot for your help.
