Ok, here's the situation. Win2k Server running IIS, AD, Exch2000, SQL2000

I keep it up to date with SP's and Patches but find that the server keeps
getting hacked and used as an "FTP" server with that stupid "Serv-U" app.
What can be done to secure this server so that this doesn't keep happening?
Is port blocking (leaving only bare necessity open) my only recourse? If so,

I'm a developer, and know only basic fundamentals of OS/IIS security.....


(P.S... I keep manually killing the app that gets installed and manually
deleting the files/app/dirs that the hack creates.)
