Im trying to configure xdebug to work with Netbeans 6.9 and php 5.3 As far as i concern i have setup xdebug properly. I can see xdebug extension from phpinfo page.
I solved this using a windows -> remote LAMP server config after reading the following post, leaving the link in case anyone finds it handy:
