My FTP site is being "attacked"

Hi,
I run a FTP server on IIS 5.1 (in XP) and lately my logs show that a
wide range of IPs have been accessing the ftp account through an
anonymous log on. I know htat I can close down anonymous access to
the FTP server but I wonder if there is another way to counter act
this? I also wonder whether anyone can shed light on why and what the
people are trying to do to or with my computer. They have created a
bunch of nonsense directories, some of which, strangely, I have been
unable to delete and appear to have no name. I am going to post a
segment of the log below just as an example. Any help would be
greatly appreciated.
