We have built a Windows 2003 server to replace one that is currently in situ but very unstable. It is a webhosting platform running IIS 6 with PHP and ASPX websites. ASPX websites work fine but any websites running PHP return a 404 error when we try to load them. We have checked permissions on the PHP folder (C:\PHP) and these are the same as those on the unstable server.
Grateful for any advice on what may be causing the issue or what we may be overlooking. Thanks.
