hello everyone
recently we add a computer with Linux red hat enterprise server 5.1
every patch that we try to deploy to the server it writes that he cannot download the file from red hat server
so i enter to the fixlet and found that her try to download a file that no longer exist in that location in red hat server
for example i try to deploy
RHSA-2009:1186 - Nspr and Nss Security, Bug Fix, and Enhancement Update - Red Hat Enterprise 5.0 (x86_64)
the link for the update is http://download.rhn.redhat.com/MANUAL_B … 2.i386.rpm

if you enter to this site you get 404 Error - File Not Found
now i have a problem because every fixlet that i want to deploy he cannt find the update in the red hat server

is there a way to fix this problem ?

thank you very much for your help
