I have had a couple of times where my server was brought to its knees because of brute force attacks on my blogs. Last week there was one that targeted the wp-login.php. While natnet put in a security measure for me, some of you may want access to the htaccess code to protect your own blogs.

You can get the code and setup information here: compliments of BulletProofSecurity. Can't say I recommend the plugin they have, (I've tried to set up the plugin, but it isn't a simple click click and done) .... but that code can save you some grief.
