Re: proxy isa server

>From my Centos machine the dns lookup works fine, I can resolve the   
mirrorlist/baseurl domains.

Yes, I can authenticate with this proxy from the centos machine in firefox.

I have tried to authenticate me, first from firefox and then I have executed yum, but the proxy refuse authentication.....

Yes, I have just tried ntlm software, but, again, the proxy refuse my authentication.
