Strange things in Yum

[Antonio Montagnani]

Friday, on one my computer in the office network, I installed

rpmforge repo, and if :

yum update all

I get

Setting up Update Process
Setting up repositories
Cannot find a valid baseurl for repo: rpmforge
Error: Cannot find a valid baseurl for repo: rpmforge


I disinstalled rpmforge but I got similar message for updates-released.

What happened and how to recover from this point (same with rpmforge 
installed or not)?

Of ourse similar problem with Yumex

At same time no problem at all on another Fedora Pc...

Tnx
