Log IP on failed login attempt

Hi,
How would one make SQL SERVER Log the IP on failed login attempt ?In SQL2005 this is done by default for failed logins and recorded in the SQL
error log. In SQL2000 you can't do it that effectively (you could get
hostname from a profiler trace but since this can be set in the connection
string it's not reliable)

I didn't find any good solutions to prevent hacking of my servers either
so I wrote a utility program to help.

BlockSSHacking runs as a Windows service protecting your SQL Server from
brute force hacking attempts coming from the Internet.
The service checks your system every 5 minutes (configurable setting)
for evidence of ongoing hacking. If such attempts are in progress then
those source addresses are blocked from future access to your server
(quickly leading to you recovering your bandwidth).
BlockSSHacking notifies you via email when it has blocked someone from
hacking your system.
