For some reason, the server stops accepting all IIS traffic.


mean?

Are you failing to connect? Or getting authentication errors via FTP/HTTP?
Or something else?

No one can connect via FTP at all. Web service is also dead. Stays that way until the server is restarted.

Reason I ask is that I've seen Win2K disable accounts after enough incorrect
password attempts. If someone is running a dictionary attack against your
server, they could be tripping this functionality. You could verify this by
checking to see if the account is disabled.

It's not account related. It's just someone trying to get in so they can dump files in the FTP directory. The failed login attempts happen about 300 times in a 2 minute period. That somehow (I think) sends FTP & HTTP offline.
