About the PWS:
I have an apache and IIS installed on 2 machines (IIS for asp's). I think you have 2 options
- either set a different port for .asp and .php files
- or stop PWS (go to processes and stop it there) and then strat apache
I always do the last. IIS (and probably PWS as well) will be default be started on startup, but since i hardly write asp anymore, i've just changed the start of that process to manual, so that no webserver is started on startup.
