As of yesterday, traffic to my site (on my leased W2k Server) has trippled
from what it had normally been for several months. I suspect abuse.

How can I 1) analyze and 2) block offending hits to my site? I would
imagine that IIS will allow me to block IP addresses once I've identified
them as offensive. Finally, is there a way for W2k to automatically guard
against this or are there 3rd party utilities available?

Thanks in Advance.
