I am using MySQL Administrator on Windows 2000. The setting is under "Startup Variables" and tab "Networking" somewhere near the bottom of the page. If you enable the option, it will write a line max_connect_errors=XX in the my.ini file in your MySQL system directory. Removing the line from my.ini should disable the host block feature.
