hello,
we have a wsus server with 140 client connected, suddenly all windows 2003 sp2 x64 servers "130 server" couldn't report or download updates from the server, however only 10 windows 2008 r2 servers are working without any problems with report & downloading updates
we have already tried to reset wsus components

and we have enabled the extending logging and couldn;t find any error/warning/fatal in windows update log
