apache is the best, if you are gonna learn a webserver may as well make it apache. does your script use php5 because i had apache configured with php5 and some scripts wouldn't work, but work fine with php4. either way configing apache and php4/5 is not really hard but would be a little time consuming at first. you can make iis work with php, do you have access to windows server 2000 or 2003?
