They are generating 404s on my site

How does one track down where this is coming from?:

211.101.236.79 - - [08/Jul/2001:00:30:06 -0500] "GET /cars/honda/two/ HTTP/1.0" 404 306 "-" "Mozilla/3.0 (compatible; Indy Library)"

I believe their spider is haivng problem s because it is going to my categories, but forcing them to lowercase (as seen above). Instead, all of my categories begin with an uppercase (/Cars/Honda/Two/) I thought I could inform them that their spider is not finding any of my pages because it is forcing itself to look at lowercase subdirectories.. (Google is finding my upcase directories and pages just fine)... Any help on this would be greatly appreciated.

It's coming from someplace in China, I posted about it early this morning:

[webmasterworld.com...]

It's picking up html files that are not linked to, and some that are not even there. /Graphics/ is a directory capitalized, and it picked up

/graphics/filename.html

No such file or directory exists. It's a little confused, it looks like.
