New versions of kazaa can randomly pick ports. The solution isn't
necessarily to block kazaa, it's to fire employees or punish children that
you have told NOT to use kazaa and they refuse to obey.
Also, depending on which operating system you're using, you can also put
restrictions on the users that won't allow them to run or install it, then
also block not only ftp (preventing them from downloading it) but uninstall
any copies. Also, go to http://rr.sans.org and look at that one story of a
small network being compromised by warez type people who were using the
business' servers to store their warez and illegally-gained software.
Also, if this is a business, there's legal ramifications. Copyright holders
can sue you if they find the stuff on your network, whether you put it there
or someone else did. That's something to think about.
Please reply and give client operating systems so I can tell you how to
