fm server 9 install won"t connect to iis

win 2000 server single machine install, i gave up trying the 2 machine
install.
on the filemaker server admin console -> filemaker server overview -
>edit server deployment
->enable web publishing and php->deployment type = single machine ->
web server type selects IIS-> web server test failed

then it asks for the the host and port. i have tried 0.0.0.0 80,
127.0.0.1 80, 192.168.100.111 80

nothing works.... it recognized IIS, but then doesnt work.... syntax
error? IIS setup error? what do you think?
