Windows Server 2003...PHP problem [RESOLVED]

I don't know if anyone can help me, but if anyone is familiar with windows server 2003 standard, is there a way to set a file to be accessible and writable by all anonymous users, rather than just users of the domain. I have a page to submit to a "message board" but when i try it I get:

Warning: fopen(./boarddata.php): failed to open stream: Permission denied in F:\SuperMotorSports\messageboard\action.php on line 4

Warning: fwrite(): supplied argument is not a valid stream resource in F:\SuperMotorSports\messageboard\action.php on line 21

Warning: fclose(): supplied argument is not a valid stream resource in F:\SuperMotorSports\messageboard\action.php on line 22

could it be a coding problem or a server security issue, because it worked when i was hosting with Apache Server.
Thanks for any help anyone could offer.
the site is at SuperMotorSports.com if anyone would need to view it for seeing what's going on!

ok, nevermind, I set the security to allow everyone to write to the page.
