I'm not an expert on this top but... The traditional place to start debugging a problem like this is to try various combinations of the following three directives in httpd.conf: Win32DisableAcceptEx EnableSendfile Off EnableMMAP Off If any of those works, it probably means that apache is having difficulties with your network drivers/firewalls/etc. And in addition, you should certainly move to the latest 2.2 release. 2.0.45 is very old.
