Windows server 2003 and php v5 IIS V6

Hi, I've installed IIS 6 and configured for a website. I've installed and configured php 5. I was initially getting 401.3 Forbidden error messages in the browser. But after changing the permissions, I now just get the: 'Internet Explorer cannot display the webpage'. Any ideas, or has anyone experienced similar issues before?
