Free Windows Isp Panel

do you recommend any free open source software for isp control panel that i can use to manage my domain.

i want to lease a dedicated server with windows 2003 server and well, i looked everywhere and there arent any open source free scripts in .asp that are distributed for free as open source under GPL license. so im giving up soon but i wanted to check with you guys since you know alot about hosting wallpaper websites and perhaps you might have some information that might help me
