nasty suspicion? My server gets hit with people trying to access windows file sharing ports, ssh ports, web site, smtp for spam, etc every day and all day long. It's just random people making stupid attempts from somewhere in russia, korea, china, etc. I have stuff in place to block those attempts... firewall, block lists, etc. Is this suspicion someone you know? Otherwise, I would usually doubt that someone is genuinely making it in...
As for your httpd.conf file... yeah, you should be able to use pacifist to get a default copy. I have not checked or tried that myself, but I would imagine there is a copy of httpd.conf in the install package. As for the whole apache module... it is there, but I don't know how much you will go through to get those files back in place.
