PWS 4 Win98 and PHP, "The page cannot be displayed"

Hi, I have php-4.3.2-installer.exe and run it at home on my win2k machine and all works fine with no additional work requried. Im trying to put it on my work machine, i ran the install, selected the appropriate install option, gave my default cgi-bin folder read, execute and script permission. Now everytime I try and view a php page i get 'The page cannot be displayed error' on a page title, cannot find sever. Ive read and tried all sorts now, ive ran out of ideas and patients. Any help greatly appriciated, I presume its looking in the rite place as if I turn of the execute permission I get a differenct 'forbiddin' error page. Please Help Regards Craig
