i have a specific IP that's trying to login to my server via the SA login. anyone know a quick/easy way to ban the ip either via server 2003 or sql?

only router we have is a P.O.S. WRT54g linksys, so firewall (atm) is not an option :(

Is the IP coming from outside your organization?
Change default port number from 1433 to another port number and change all internal application to connect to new port number.

A software firewall would probably do the trick. I've used Kerio WinRoute Firewall professionally for several years (a while back though) and never had any problems: http://www.kerio.eu/kwf_home.html

And do make sure hat your SA password is of substantial complexity, a GUID maybe?

yeah, it's coming from outside. i found a cheap software firewall that'll allow me to block specific ips, so that was step one. it's call "Find 'n block" for anyone who cares.

i disabled the SA login, i have equivalant privlages so i dont really need it. if i ever do i can always re-enable it.

next step is as peso suggested, i'm going to change the sql port to something different, but need to find some time to go though everything to make sure i have minimal down time.


Thanks for the advice!

Never ever use port 1433 for systems that are accessible externally.
